Built-in Functions
==================
2008-05-05 18:05:32 -03:00
The Python interpreter has a number of functions and types built into it that
are always available. They are listed here in alphabetical order.

2007-08-15 11:28:22 -03:00
.. function:: abs(x)
Return the absolute value of a number. The argument may be an
2007-08-15 11:28:22 -03:00
integer or a floating point number. If the argument is a complex number, its
magnitude is returned.
.. function:: all(iterable)
Return ``True`` if all elements of the *iterable* are true (or if the iterable
is empty). Equivalent to::
2007-08-15 11:28:22 -03:00
def all(iterable):
for element in iterable:
if not element:
return False
return True
.. function:: any(iterable)
Return ``True`` if any element of the *iterable* is true. If the iterable
is empty, return ``False``. Equivalent to::
2007-08-15 11:28:22 -03:00
def any(iterable):
for element in iterable:
if element:
return True
return False
.. function:: ascii(object)
As :func:`repr`, return a string containing a printable representation of an
object, but escape the non-ASCII characters in the string returned by
:func:`repr` using ``\x``, ``\u`` or ``\U`` escapes. This generates a string
similar to that returned by :func:`repr` in Python 2.
2007-08-15 11:28:22 -03:00
.. function:: bin(x)
Convert an integer number to a binary string. The result is a valid Python
expression. If *x* is not a Python :class:`int` object, it has to define an
:meth:`__index__` method that returns an integer.
.. function:: bool([x])
Convert a value to a Boolean, using the standard :ref:`truth testing
procedure <truth>`. If *x* is false or omitted, this returns ``False``;
otherwise it returns ``True``. :class:`bool` is also a class, which is a
subclass of :class:`int` (see :ref:`typesnumeric`). Class :class:`bool`
cannot be subclassed further. Its only instances are ``False`` and
``True`` (see :ref:`bltin-boolean-values`).
2007-08-15 11:28:22 -03:00
.. index:: pair: Boolean; type
.. _func-bytearray:
.. function:: bytearray([source[, encoding[, errors]]])
2007-11-22 10:16:00 -04:00
Return a new array of bytes. The :class:`bytearray` type is a mutable
sequence of integers in the range 0 <= x < 256. It has most of the usual
methods of mutable sequences, described in :ref:`typesseq-mutable`, as well
as most methods that the :class:`bytes` type has, see :ref:`bytes-methods`.
The optional *source* parameter can be used to initialize the array in a few
different ways:
* If it is a *string*, you must also give the *encoding* (and optionally,
*errors*) parameters; :func:`bytearray` then converts the string to
bytes using :meth:`str.encode`.
* If it is an *integer*, the array will have that size and will be
initialized with null bytes.
* If it is an object conforming to the *buffer* interface, a read-only buffer
of the object will be used to initialize the bytes array.
* If it is an *iterable*, it must be an iterable of integers in the range
``0 <= x < 256``, which are used as the initial contents of the array.
Without an argument, an array of size 0 is created.
See also :ref:`binaryseq` and :ref:`typebytearray`.
.. _func-bytes:
.. function:: bytes([source[, encoding[, errors]]])
Return a new "bytes" object, which is an immutable sequence of integers in
the range ``0 <= x < 256``. :class:`bytes` is an immutable version of
:class:`bytearray` -- it has the same non-mutating methods and the same
indexing and slicing behavior.
2009-01-03 17:18:54 -04:00
2009-04-29 03:37:12 -03:00
Accordingly, constructor arguments are interpreted as for :func:`bytearray`.
Bytes objects can also be created with literals, see :ref:`strings`.
See also :ref:`binaryseq`, :ref:`typebytes`, and :ref:`bytes-methods`.
.. function:: callable(object)
Return :const:`True` if the *object* argument appears callable,
:const:`False` if not. If this returns true, it is still possible that a
call fails, but if it is false, calling *object* will never succeed.
Note that classes are callable (calling a class returns a new instance);
instances are callable if their class has a :meth:`__call__` method.
.. versionadded:: 3.2
This function was first removed in Python 3.0 and then brought back
in Python 3.2.
2007-08-15 11:28:22 -03:00
.. function:: chr(i)
Return the string representing a character whose Unicode codepoint is the integer
*i*. For example, ``chr(97)`` returns the string ``'a'``. This is the
inverse of :func:`ord`. The valid range for the argument is from 0 through
1,114,111 (0x10FFFF in base 16). :exc:`ValueError` will be raised if *i* is
outside that range.
2007-08-15 11:28:22 -03:00
.. function:: classmethod(function)
Return a class method for *function*.
A class method receives the class as implicit first argument, just like an
instance method receives the instance. To declare a class method, use this
idiom::
class C:
@classmethod
def f(cls, arg1, arg2, ...): ...

The ``@classmethod`` form is a function :term:`decorator` -- see the description
of function definitions in :ref:`function` for details.
2007-08-15 11:28:22 -03:00
It can be called either on the class (such as ``C.f()``) or on an instance (such
as ``C().f()``). The instance is ignored except for its class. If a class
method is called for a derived class, the derived class object is passed as the
implied first argument.
Class methods are different than C++ or Java static methods. If you want those,
see :func:`staticmethod` in this section.
For more information on class methods, consult the documentation on the standard
type hierarchy in :ref:`types`.
.. function:: compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1)
2007-08-15 11:28:22 -03:00
Compile the *source* into a code or AST object. Code objects can be executed
by :func:`exec` or :func:`eval`. *source* can either be a normal string, a
byte string, or an AST object. Refer to the :mod:`ast` module documentation
for information on how to work with AST objects.
The *filename* argument should give the file from which the code was read;
pass some recognizable value if it wasn't read from a file (``'<string>'`` is
commonly used).
The *mode* argument specifies what kind of code must be compiled; it can be
``'exec'`` if *source* consists of a sequence of statements, ``'eval'`` if it
consists of a single expression, or ``'single'`` if it consists of a single
interactive statement (in the latter case, expression statements that
evaluate to something other than ``None`` will be printed).
2007-08-15 11:28:22 -03:00
The optional arguments *flags* and *dont_inherit* control which future
statements (see :pep:`236`) affect the compilation of *source*. If neither
is present (or both are zero) the code is compiled with those future
statements that are in effect in the code that is calling compile. If the
*flags* argument is given and *dont_inherit* is not (or is zero) then the
2007-08-15 11:28:22 -03:00
future statements specified by the *flags* argument are used in addition to
those that would be used anyway. If *dont_inherit* is a non-zero integer then
the *flags* argument is it -- the future statements in effect around the call
to compile are ignored.

Future statements are specified by bits which can be bitwise ORed together to
2007-08-15 11:28:22 -03:00
specify multiple statements. The bitfield required to specify a given feature
can be found as the :attr:`~__future__._Feature.compiler_flag` attribute on
the :class:`~__future__._Feature` instance in the :mod:`__future__` module.
2007-08-15 11:28:22 -03:00
The argument *optimize* specifies the optimization level of the compiler; the
default value of ``-1`` selects the optimization level of the interpreter as
given by :option:`-O` options. Explicit levels are ``0`` (no optimization;
``__debug__`` is true), ``1`` (asserts are removed, ``__debug__`` is false)
or ``2`` (docstrings are removed too).
This function raises :exc:`SyntaxError` if the compiled source is invalid,

When compiling a string with multi-line code in ``'single'`` or
``'eval'`` mode, input must be terminated by at least one newline
character. This is to facilitate detection of incomplete and complete
statements in the :mod:`code` module.
.. versionchanged:: 3.2
Allowed use of Windows and Mac newlines. Also input in ``'exec'`` mode
does not have to end in a newline anymore. Added the *optimize* parameter.
2007-08-15 11:28:22 -03:00
.. function:: complex([real[, imag]])
Create a complex number with the value *real* + *imag*\*j or convert a string or
number to a complex number. If the first parameter is a string, it will be
interpreted as a complex number and the function must be called without a second
parameter. The second parameter can never be a string. Each argument may be any
numeric type (including complex). If *imag* is omitted, it defaults to zero and
the function serves as a numeric conversion function like :func:`int`
and :func:`float`. If both arguments are omitted, returns ``0j``.
2007-08-15 11:28:22 -03:00
.. note::
When converting from a string, the string must not contain whitespace
around the central ``+`` or ``-`` operator. For example,
``complex('1+2j')`` is fine, but ``complex('1 + 2j')`` raises
:exc:`ValueError`.
2007-08-15 11:28:22 -03:00
The complex type is described in :ref:`typesnumeric`.
.. function:: delattr(object, name)
This is a relative of :func:`setattr`. The arguments are an object and a
string. The string must be the name of one of the object's attributes. The
function deletes the named attribute, provided the object allows it. For
example, ``delattr(x, 'foobar')`` is equivalent to ``del x.foobar``.
.. _func-dict:
.. function:: dict(**kwarg)
dict(mapping, **kwarg)
dict(iterable, **kwarg)
2007-08-15 11:28:22 -03:00
:noindex:
Create a new dictionary. The :class:`dict` object is the dictionary class.
See :class:`dict` and :ref:`typesmapping` for documentation about this
class.
2007-08-15 11:28:22 -03:00
For other containers see the built-in :class:`list`, :class:`set`, and
:class:`tuple` classes, as well as the :mod:`collections` module.
2007-08-15 11:28:22 -03:00
.. function:: dir([object])
Without arguments, return the list of names in the current local scope. With an
argument, attempt to return a list of valid attributes for that object.
If the object has a method named :meth:`__dir__`, this method will be called and
must return the list of attributes. This allows objects that implement a custom
:func:`__getattr__` or :func:`__getattribute__` function to customize the way
:func:`dir` reports their attributes.
If the object does not provide :meth:`__dir__`, the function tries its best to
gather information from the object's :attr:`__dict__` attribute, if defined, and
from its type object. The resulting list is not necessarily complete, and may
be inaccurate when the object has a custom :func:`__getattr__`.
The default :func:`dir` mechanism behaves differently with different types of
objects, as it attempts to produce the most relevant, rather than complete,
information:
* If the object is a module object, the list contains the names of the module's
attributes.
* If the object is a type or class object, the list contains the names of its
attributes, and recursively of the attributes of its bases.
* Otherwise, the list contains the object's attributes' names, the names of its
class's attributes, and recursively of the attributes of its class's base
classes.

.. note::
Because :func:`dir` is supplied primarily as a convenience for use at an
interactive prompt, it tries to supply an interesting set of names more
than it tries to supply a rigorously or consistently defined set of names,
and its detailed behavior may change across releases. For example,
metaclass attributes are not in the result list when the argument is a
class.

.. function:: divmod(a, b)
Take two (non complex) numbers as arguments and return a pair of numbers
consisting of their quotient and remainder when using integer division. With
mixed operand types, the rules for binary arithmetic operators apply. For
integers, the result is the same as ``(a // b, a % b)``. For floating point
numbers the result is ``(q, a % b)``, where *q* is usually ``math.floor(a /
b)`` but may be 1 less than that. In any case ``q * b + a % b`` is very
close to *a*, if ``a % b`` is non-zero it has the same sign as *b*, and ``0
<= abs(a % b) < abs(b)``.

2008-09-01 21:31:15 -03:00
This function can also be used to execute arbitrary code objects (such as
those created by :func:`compile`). In this case pass a code object instead
of a string. If the code object has been compiled with ``'exec'`` as the
*mode* argument, :func:`eval`\'s return value will be ``None``.
2007-08-15 11:28:22 -03:00
Hints: dynamic execution of statements is supported by the :func:`exec`
function. The :func:`globals` and :func:`locals` functions
returns the current global and local dictionary, respectively, which may be
useful to pass around for use by :func:`eval` or :func:`exec`.
See :func:`ast.literal_eval` for a function that can safely evaluate strings
with expressions containing only literals.
2007-08-15 11:28:22 -03:00
.. function:: exec(object[, globals[, locals]])
2008-11-11 17:43:42 -04:00
This function supports dynamic execution of Python code. *object* must be
either a string or a code object. If it is a string, the string is parsed as
a suite of Python statements which is then executed (unless a syntax error
occurs). [#]_ If it is a code object, it is simply executed. In all cases,
the code that's executed is expected to be valid as file input (see the
section "File input" in the Reference Manual). Be aware that the
:keyword:`return` and :keyword:`yield` statements may not be used outside of
function definitions even within the context of code passed to the
:func:`exec` function. The return value is ``None``.
2007-08-15 11:28:22 -03:00
In all cases, if the optional parts are omitted, the code is executed in the
current scope. If only *globals* is provided, it must be a dictionary, which
will be used for both the global and the local variables. If *globals* and
*locals* are given, they are used for the global and local variables,
respectively. If provided, *locals* can be any mapping object. Remember
that at module level, globals and locals are the same dictionary. If exec
gets two separate objects as *globals* and *locals*, the code will be
executed as if it were embedded in a class definition.
2007-08-15 11:28:22 -03:00
If the *globals* dictionary does not contain a value for the key
``__builtins__``, a reference to the dictionary of the built-in module
:mod:`builtins` is inserted under that key. That way you can control what
2007-08-15 11:28:22 -03:00
builtins are available to the executed code by inserting your own
``__builtins__`` dictionary into *globals* before passing it to :func:`exec`.
.. note::
The built-in functions :func:`globals` and :func:`locals` return the current
global and local dictionary, respectively, which may be useful to pass around
for use as the second and third argument to :func:`exec`.
.. note::
2007-08-15 11:28:22 -03:00
The default *locals* act as described for function :func:`locals` below:
modifications to the default *locals* dictionary should not be attempted.
Pass an explicit *locals* dictionary if you need to see effects of the
code on *locals* after function :func:`exec` returns.
2007-08-15 11:28:22 -03:00
.. function:: filter(function, iterable)
Construct an iterator from those elements of *iterable* for which *function*
returns true. *iterable* may be either a sequence, a container which

supports iteration, or an iterator. If *function* is ``None``, the identity
function is assumed, that is, all elements of *iterable* that are false are
removed.
2007-08-15 11:28:22 -03:00
Note that ``filter(function, iterable)`` is equivalent to the generator
expression ``(item for item in iterable if function(item))`` if function is
not ``None`` and ``(item for item in iterable if item)`` if function is
``None``.
2007-08-15 11:28:22 -03:00
See :func:`itertools.filterfalse` for the complementary function that returns
elements of *iterable* for which *function* returns false.
2007-08-15 11:28:22 -03:00
.. function:: float([x])
.. index::
single: NaN
single: Infinity
Convert a string or a number to floating point.
If the argument is a string, it should contain a decimal number, optionally
preceded by a sign, and optionally embedded in whitespace. The optional
sign may be ``'+'`` or ``'-'``; a ``'+'`` sign has no effect on the value
produced. The argument may also be a string representing a NaN
(not-a-number), or a positive or negative infinity. More precisely, the
input must conform to the following grammar after leading and trailing
whitespace characters are removed:
.. productionlist::
sign: "+" | "-"
infinity: "Infinity" | "inf"
nan: "nan"
2010-12-04 15:06:18 -04:00
numeric_value: `floatnumber` | `infinity` | `nan`
numeric_string: [`sign`] `numeric_value`
Here ``floatnumber`` is the form of a Python floating-point literal,
described in :ref:`floating`. Case is not significant, so, for example,
"inf", "Inf", "INFINITY" and "iNfINity" are all acceptable spellings for
positive infinity.
Otherwise, if the argument is an integer or a floating point number, a
floating point number with the same value (within Python's floating point
precision) is returned. If the argument is outside the range of a Python
float, an :exc:`OverflowError` will be raised.
For a general Python object ``x``, ``float(x)`` delegates to
``x.__float__()``.
If no argument is given, ``0.0`` is returned.
Examples::
>>> float('+1.23')
1.23
>>> float(' -12345\n')
-12345.0
>>> float('1e-003')
0.001
>>> float('+1E6')
1000000.0
>>> float('-Infinity')
-inf
2007-08-15 11:28:22 -03:00
The float type is described in :ref:`typesnumeric`.
.. index::
single: __format__
single: string; format() (built-in function)
.. function:: format(value[, format_spec])
2009-01-03 17:18:54 -04:00
Convert a *value* to a "formatted" representation, as controlled by
*format_spec*. The interpretation of *format_spec* will depend on the type
of the *value* argument, however there is a standard formatting syntax that
is used by most built-in types: :ref:`formatspec`.
2009-01-03 17:18:54 -04:00
The default *format_spec* is an empty string which usually gives the same
effect as calling :func:`str(value) <str>`.
A call to ``format(value, format_spec)`` is translated to
``type(value).__format__(format_spec)`` which bypasses the instance
dictionary when searching for the value's :meth:`__format__` method. A
:exc:`TypeError` exception is raised if the method is not found or if either
the *format_spec* or the return value are not strings.
2012-12-23 09:12:19 -04:00
.. versionadded:: 3.4
``object().__format__(format_spec)`` raises :exc:`TypeError`
if *format_spec* is not empty string.
.. _func-frozenset:
2007-08-15 11:28:22 -03:00
.. function:: frozenset([iterable])
:noindex:
Return a new :class:`frozenset` object, optionally with elements taken from
*iterable*. ``frozenset`` is a built-in class. See :class:`frozenset` and
:ref:`types-set` for documentation about this class.
2007-08-15 11:28:22 -03:00
For other containers see the built-in :class:`set`, :class:`list`,
:class:`tuple`, and :class:`dict` classes, as well as the :mod:`collections`
module.
2007-08-15 11:28:22 -03:00
.. function:: getattr(object, name[, default])
2010-10-16 15:51:05 -03:00
Return the value of the named attribute of *object*. *name* must be a string.
2007-08-15 11:28:22 -03:00
If the string is the name of one of the object's attributes, the result is the
value of that attribute. For example, ``getattr(x, 'foobar')`` is equivalent to
``x.foobar``. If the named attribute does not exist, *default* is returned if
provided, otherwise :exc:`AttributeError` is raised.
.. function:: globals()
Return a dictionary representing the current global symbol table. This is always
the dictionary of the current module (inside a function or method, this is the
module where it is defined, not the module from which it is called).
.. function:: hasattr(object, name)
The arguments are an object and a string. The result is ``True`` if the
string is the name of one of the object's attributes, ``False`` if not. (This
is implemented by calling ``getattr(object, name)`` and seeing whether it
raises an :exc:`AttributeError` or not.)
2007-08-15 11:28:22 -03:00
.. function:: hash(object)
Return the hash value of the object (if it has one). Hash values are
integers. They are used to quickly compare dictionary keys during a
dictionary lookup. Numeric values that compare equal have the same hash
value (even if they are of different types, as is the case for 1 and 1.0).
2007-08-15 11:28:22 -03:00
.. note::
For object's with custom :meth:`__hash__` methods, note that :func:`hash`
truncates the return value based on the bit width of the host machine.
See :meth:`__hash__` for details.
2007-08-15 11:28:22 -03:00
.. function:: help([object])
Invoke the built-in help system. (This function is intended for interactive
use.) If no argument is given, the interactive help system starts on the
interpreter console. If the argument is a string, then the string is looked up
as the name of a module, function, class, method, keyword, or documentation
topic, and a help page is printed on the console. If the argument is any other
kind of object, a help page on the object is generated.

.. function:: hex(x)
Convert an integer number to a hexadecimal string. The result is a valid Python
expression. If *x* is not a Python :class:`int` object, it has to define an
:meth:`__index__` method that returns an integer.
.. note::
To obtain a hexadecimal string representation for a float, use the

Two objects with non-overlapping lifetimes may have the same :func:`id`
value.

.. function:: input([prompt])
If the *prompt* argument is present, it is written to standard output without
a trailing newline. The function then reads a line from input, converts it
to a string (stripping a trailing newline), and returns that. When EOF is
read, :exc:`EOFError` is raised. Example::
2012-08-12 09:16:42 -03:00
>>> s = input('--> ') # doctest: +SKIP

If the :mod:`readline` module was loaded, then :func:`input` will use it
2007-09-12 18:29:27 -03:00
to provide elaborate line editing and history features.
.. function:: int(x=0)
int(x, base=10)
Convert a number or string *x* to an integer, or return ``0`` if no
arguments are given. If *x* is a number, return :meth:`x.__int__()
<object.__int__>`. For floating point numbers, this truncates towards zero.
If *x* is not a number or if *base* is given, then *x* must be a string,
:class:`bytes`, or :class:`bytearray` instance representing an :ref:`integer
literal <integers>` in radix *base*. Optionally, the literal can be
preceded by ``+`` or ``-`` (with no space in between) and surrounded by
whitespace. A base-n literal consists of the digits 0 to n-1, with ``a``
to ``z`` (or ``A`` to ``Z``) having
values 10 to 35. The default *base* is 10. The allowed values are 0 and 2-36.
2008-04-09 15:45:14 -03:00
Base-2, -8, and -16 literals can be optionally prefixed with ``0b``/``0B``,
``0o``/``0O``, or ``0x``/``0X``, as with integer literals in code. Base 0
means to interpret exactly as a code literal, so that the actual base is 2,
2008-04-09 15:45:14 -03:00
8, 10, or 16, and so that ``int('010', 0)`` is not legal, while
``int('010')`` is, as well as ``int('010', 8)``.
2007-08-15 11:28:22 -03:00
The integer type is described in :ref:`typesnumeric`.
.. versionchanged:: 3.4
If *base* is not an instance of :class:`int` and the *base* object has a
:meth:`base.__index__ <object.__index__>` method, that method is called
to obtain an integer for the base. Previous versions used
:meth:`base.__int__ <object.__int__>` instead of :meth:`base.__index__
<object.__index__>`.
2007-08-15 11:28:22 -03:00
.. function:: isinstance(object, classinfo)
Return true if the *object* argument is an instance of the *classinfo*
argument, or of a (direct, indirect or :term:`virtual <abstract base
class>`) subclass thereof. If *object* is not
an object of the given type, the function always returns false. If
*classinfo* is not a class (type object), it may be a tuple of type objects,
or may recursively contain other such tuples (other sequence types are not
accepted). If *classinfo* is not a type or tuple of types and such tuples,
a :exc:`TypeError` exception is raised.
2007-08-15 11:28:22 -03:00
.. function:: issubclass(class, classinfo)
Return true if *class* is a subclass (direct, indirect or :term:`virtual
<abstract base class>`) of *classinfo*. A
2007-08-15 11:28:22 -03:00
class is considered a subclass of itself. *classinfo* may be a tuple of class
objects, in which case every entry in *classinfo* will be checked. In any other
case, a :exc:`TypeError` exception is raised.
.. function:: iter(object[, sentinel])
2007-08-15 11:28:22 -03:00
Return an :term:`iterator` object. The first argument is interpreted very
differently depending on the presence of the second argument. Without a
second argument, *object* must be a collection object which supports the
iteration protocol (the :meth:`__iter__` method), or it must support the
sequence protocol (the :meth:`__getitem__` method with integer arguments
starting at ``0``). If it does not support either of those protocols,
:exc:`TypeError` is raised. If the second argument, *sentinel*, is given,
then *object* must be a callable object. The iterator created in this case
2012-10-12 07:42:08 -03:00
will call *object* with no arguments for each call to its
:meth:`~iterator.__next__` method; if the value returned is equal to
*sentinel*, :exc:`StopIteration` will be raised, otherwise the value will
be returned.

affect the values of local and free variables used by the interpreter.
2007-08-15 11:28:22 -03:00
.. function:: map(function, iterable, ...)
Return an iterator that applies *function* to every item of *iterable*,
yielding the results. If additional *iterable* arguments are passed,
*function* must take that many arguments and is applied to the items from all
2008-05-05 18:04:12 -03:00
iterables in parallel. With multiple iterables, the iterator stops when the
shortest iterable is exhausted. For cases where the function inputs are
already arranged into argument tuples, see :func:`itertools.starmap`\.
2008-05-05 18:04:12 -03:00
2007-08-15 11:28:22 -03:00
.. function:: max(iterable, *[, default, key])
max(arg1, arg2, *args[, key])
2007-08-15 11:28:22 -03:00
Return the largest item in an iterable or the largest of two or more
arguments.
If one positional argument is provided, it should be an :term:`iterable`.
The largest item in the iterable is returned. If two or more positional
arguments are provided, the smallest of the positional arguments is
returned.
2007-08-15 11:28:22 -03:00
There are two optional keyword-only arguments. The *key* argument specifies
a one-argument ordering function like that used for :meth:`list.sort`. The
*default* argument specifies an object to return if the provided iterable is
empty. If the iterable is empty and *default* is not provided, a
:exc:`ValueError` is raised.
2007-08-15 11:28:22 -03:00
2010-10-06 07:26:05 -03:00
If multiple items are maximal, the function returns the first one
encountered. This is consistent with other sort-stability preserving tools
such as ``sorted(iterable, key=keyfunc, reverse=True)[0]`` and
``heapq.nlargest(1, iterable, key=keyfunc)``.
2007-08-15 11:28:22 -03:00
.. _func-memoryview:
.. function:: memoryview(obj)
2008-09-10 18:02:02 -03:00
:noindex:
Return a "memory view" object created from the given argument. See
:ref:`typememoryview` for more information.
.. function:: min(iterable, *[, default, key])
min(arg1, arg2, *args[, key])
Return the smallest item in an iterable or the smallest of two or more
arguments.
2007-08-15 11:28:22 -03:00
If one positional argument is provided, it should be an :term:`iterable`.
The smallest item in the iterable is returned. If two or more positional
arguments are provided, the smallest of the positional arguments is
returned.
2007-08-15 11:28:22 -03:00
There are two optional keyword-only arguments. The *key* argument specifies
a one-argument ordering function like that used for :meth:`list.sort`. The
*default* argument specifies an object to return if the provided iterable is
empty. If the iterable is empty and *default* is not provided, a
:exc:`ValueError` is raised.
2007-08-15 11:28:22 -03:00
2010-10-06 07:26:05 -03:00
If multiple items are minimal, the function returns the first one
encountered. This is consistent with other sort-stability preserving tools
such as ``sorted(iterable, key=keyfunc)[0]`` and ``heapq.nsmallest(1,
iterable, key=keyfunc)``.
2007-08-15 11:28:22 -03:00
.. function:: next(iterator[, default])
2012-10-12 07:42:08 -03:00
Retrieve the next item from the *iterator* by calling its
:meth:`~iterator.__next__` method. If *default* is given, it is returned
if the iterator is exhausted, otherwise :exc:`StopIteration` is raised.
2007-08-15 11:28:22 -03:00
.. function:: object()
Return a new featureless object. :class:`object` is a base for all classes.
It has the methods that are common to all instances of Python classes. This
function does not accept any arguments.
.. note::
:class:`object` does *not* have a :attr:`~object.__dict__`, so you can't
assign arbitrary attributes to an instance of the :class:`object` class.
2007-08-15 11:28:22 -03:00
.. function:: oct(x)
Convert an integer number to an octal string. The result is a valid Python
expression. If *x* is not a Python :class:`int` object, it has to define an
:meth:`__index__` method that returns an integer.
.. index::
single: file object; open() built-in function
.. function:: open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None, closefd=True, opener=None)
2007-08-15 11:28:22 -03:00
Open *file* and return a corresponding :term:`file object`. If the file
cannot be opened, an :exc:`OSError` is raised.
2009-01-03 17:18:54 -04:00
2010-08-30 09:46:09 -03:00
*file* is either a string or bytes object giving the pathname (absolute or
relative to the current working directory) of the file to be opened or
an integer file descriptor of the file to be wrapped. (If a file descriptor
is given, it is closed when the returned I/O object is closed, unless
*closefd* is set to ``False``.)
*mode* is an optional string that specifies the mode in which the file is
2010-08-30 09:46:09 -03:00
opened. It defaults to ``'r'`` which means open for reading in text mode.
Other common values are ``'w'`` for writing (truncating the file if it
already exists), ``'x'`` for exclusive creation and ``'a'`` for appending
(which on *some* Unix systems, means that *all* writes append to the end of
the file regardless of the current seek position). In text mode, if
*encoding* is not specified the encoding used is platform dependent:
``locale.getpreferredencoding(False)`` is called to get the current locale
encoding. (For reading and writing raw bytes use binary mode and leave
*encoding* unspecified.) The available modes are:
========= ===============================================================
Character Meaning
========= ===============================================================
``'r'`` open for reading (default)

``'b'`` binary mode

``'t'`` text mode (default)
``'+'`` open a disk file for updating (reading and writing)
``'U'`` :term:`universal newlines` mode (deprecated)
========= ===============================================================
2010-08-30 09:46:09 -03:00
The default mode is ``'r'`` (open for reading text, synonym of ``'rt'``).
For binary read-write access, the mode ``'w+b'`` opens and truncates the file
to 0 bytes. ``'r+b'`` opens the file without truncation.
2010-08-30 09:46:09 -03:00
As mentioned in the :ref:`io-overview`, Python distinguishes between binary
and text I/O. Files opened in binary mode (including ``'b'`` in the *mode*
argument) return contents as :class:`bytes` objects without any decoding. In
text mode (the default, or when ``'t'`` is included in the *mode* argument),
the contents of the file are returned as :class:`str`, the bytes having been
first decoded using a platform-dependent encoding or using the specified
*encoding* if given.
2010-08-30 09:46:09 -03:00
.. note::
Python doesn't depend on the underlying operating system's notion of text
2011-10-19 04:58:56 -03:00
files; all the processing is done by Python itself, and is therefore
platform-independent.
2010-08-30 09:46:09 -03:00
*buffering* is an optional integer used to set the buffering policy. Pass 0
to switch buffering off (only allowed in binary mode), 1 to select line
buffering (only usable in text mode), and an integer > 1 to indicate the size
in bytes of a fixed-size chunk buffer. When no *buffering* argument is
given, the default buffering policy works as follows:
2010-08-30 09:46:09 -03:00
* Binary files are buffered in fixed-size chunks; the size of the buffer is
chosen using a heuristic trying to determine the underlying device's "block
size" and falling back on :attr:`io.DEFAULT_BUFFER_SIZE`. On many systems,
the buffer will typically be 4096 or 8192 bytes long.
* "Interactive" text files (files for which :meth:`~io.IOBase.isatty`
returns ``True``) use line buffering. Other text files use the policy
described above for binary files.
2009-01-03 17:18:54 -04:00
*encoding* is the name of the encoding used to decode or encode the file.
This should only be used in text mode. The default encoding is platform
2009-03-22 23:44:58 -03:00
dependent (whatever :func:`locale.getpreferredencoding` returns), but any
encoding supported by Python can be used. See the :mod:`codecs` module for
the list of supported encodings.
*errors* is an optional string that specifies how encoding and decoding
errors are to be handled--this cannot be used in binary mode.
A variety of standard error handlers are available, though any
error handling name that has been registered with
:func:`codecs.register_error` is also valid. The standard names
are:
* ``'strict'`` to raise a :exc:`ValueError` exception if there is
an encoding error. The default value of ``None`` has the same
effect.
* ``'ignore'`` ignores errors. Note that ignoring encoding errors
can lead to data loss.
* ``'replace'`` causes a replacement marker (such as ``'?'``) to be inserted
where there is malformed data.
* ``'surrogateescape'`` will represent any incorrect bytes as code
points in the Unicode Private Use Area ranging from U+DC80 to
U+DCFF. These private code points will then be turned back into
the same bytes when the ``surrogateescape`` error handler is used
when writing data. This is useful for processing files in an
unknown encoding.
* ``'xmlcharrefreplace'`` is only supported when writing to a file.
Characters not supported by the encoding are replaced with the
appropriate XML character reference ``&#nnn;``.
* ``'backslashreplace'`` (also only supported when writing)
replaces unsupported characters with Python's backslashed escape
sequences.
.. index::
single: universal newlines; open() built-in function
*newline* controls how :term:`universal newlines` mode works (it only
2012-08-15 12:05:36 -03:00
applies to text mode). It can be ``None``, ``''``, ``'\n'``, ``'\r'``, and
``'\r\n'``. It works as follows:
2012-08-14 04:39:07 -03:00
* When reading input from the stream, if *newline* is ``None``, universal
newlines mode is enabled. Lines in the input can end in ``'\n'``,
``'\r'``, or ``'\r\n'``, and these are translated into ``'\n'`` before
being returned to the caller. If it is ``''``, universal newlines mode is
2012-08-14 04:39:07 -03:00
enabled, but line endings are returned to the caller untranslated. If it
has any of the other legal values, input lines are only terminated by the
given string, and the line ending is returned to the caller untranslated.
* When writing output to the stream, if *newline* is ``None``, any ``'\n'``
characters written are translated to the system default line separator,
:data:`os.linesep`. If *newline* is ``''`` or ``'\n'``, no translation
takes place. If *newline* is any of the other legal values, any ``'\n'``
characters written are translated to the given string.
If *closefd* is ``False`` and a file descriptor rather than a filename was
given, the underlying file descriptor will be kept open when the file is
closed. If a filename is given *closefd* has no effect and must be ``True``
(the default).
A custom opener can be used by passing a callable as *opener*. The underlying
file descriptor for the file object is then obtained by calling *opener* with
(*file*, *flags*). *opener* must return an open file descriptor (passing
:mod:`os.open` as *opener* results in functionality similar to passing
``None``).
The newly created file is :ref:`non-inheritable <fd_inheritance>`.
The following example uses the :ref:`dir_fd <dir_fd>` parameter of the
:func:`os.open` function to open a file relative to a given directory::
>>> import os
>>> dir_fd = os.open('somedir', os.O_RDONLY)
>>> def opener(path, flags):
... return os.open(path, flags, dir_fd=dir_fd)
...
>>> with open('spamspam.txt', 'w', opener=opener) as f:
... print('This will be written to somedir/spamspam.txt', file=f)
...
>>> os.close(dir_fd) # don't leak a file descriptor
The type of :term:`file object` returned by the :func:`open` function
2012-08-17 21:39:21 -03:00
depends on the mode. When :func:`open` is used to open a file in a text
mode (``'w'``, ``'r'``, ``'wt'``, ``'rt'``, etc.), it returns a subclass of
:class:`io.TextIOBase` (specifically :class:`io.TextIOWrapper`). When used
to open a file in a binary mode with buffering, the returned class is a
subclass of :class:`io.BufferedIOBase`. The exact class varies: in read
binary mode, it returns a :class:`io.BufferedReader`; in write binary and
append binary modes, it returns a :class:`io.BufferedWriter`, and in
read/write mode, it returns a :class:`io.BufferedRandom`. When buffering is
disabled, the raw stream, a subclass of :class:`io.RawIOBase`,
:class:`io.FileIO`, is returned.

2007-08-15 11:28:22 -03:00
.. function:: ord(c)
Given a string representing one Unicode character, return an integer
representing the Unicode code
point of that character. For example, ``ord('a')`` returns the integer ``97``
and ``ord('\u2020')`` returns ``8224``. This is the inverse of :func:`chr`.
2007-08-15 11:28:22 -03:00
.. function:: pow(x, y[, z])
Return *x* to the power *y*; if *z* is present, return *x* to the power *y*,
modulo *z* (computed more efficiently than ``pow(x, y) % z``). The two-argument
form ``pow(x, y)`` is equivalent to using the power operator: ``x**y``.
The arguments must have numeric types. With mixed operand types, the
coercion rules for binary arithmetic operators apply. For :class:`int`
operands, the result has the same type as the operands (after coercion)
unless the second argument is negative; in that case, all arguments are
converted to float and a float result is delivered. For example, ``10**2``
returns ``100``, but ``10**-2`` returns ``0.01``. If the second argument is
negative, the third argument must be omitted. If *z* is present, *x* and *y*
must be of integer types, and *y* must be non-negative.
2007-08-15 11:28:22 -03:00
2012-09-14 00:35:09 -03:00
.. function:: print(*objects, sep=' ', end='\\n', file=sys.stdout, flush=False)
Print *objects* to the stream *file*, separated by *sep* and followed by
*end*. *sep*, *end* and *file*, if present, must be given as keyword
arguments.
All non-keyword arguments are converted to strings like :func:`str` does and
written to the stream, separated by *sep* and followed by *end*. Both *sep*
and *end* must be strings; they can also be ``None``, which means to use the
default values. If no *objects* are given, :func:`print` will just write
*end*.
The *file* argument must be an object with a ``write(string)`` method; if it
is not present or ``None``, :data:`sys.stdout` will be used. Whether output
is buffered is usually determined by *file*, but if the *flush* keyword
argument is true, the stream is forcibly flushed.
.. versionchanged:: 3.3
Added the *flush* keyword argument.
.. function:: property(fget=None, fset=None, fdel=None, doc=None)
2007-08-15 11:28:22 -03:00
Return a property attribute.
2007-08-15 11:28:22 -03:00
*fget* is a function for getting an attribute value, likewise *fset* is a
function for setting, and *fdel* a function for del'ing, an attribute. Typical
2010-08-02 16:23:34 -03:00
use is to define a managed attribute ``x``::

turns the :meth:`voltage` method into a "getter" for a read-only attribute
with the same name.
A property object has :attr:`~property.getter`, :attr:`~property.setter`,
and :attr:`~property.deleter` methods usable as decorators that create a
copy of the property with the corresponding accessor function set to the
decorated function. This is best explained with an example::

@property
def x(self):
"""I'm the 'x' property."""
return self._x
@x.setter
def x(self, value):
self._x = value
@x.deleter
def x(self):
del self._x
This code is exactly equivalent to the first example. Be sure to give the
additional functions the same name as the original property (``x`` in this
case.)
The returned property also has the attributes ``fget``, ``fset``, and
``fdel`` corresponding to the constructor arguments.
2007-08-15 11:28:22 -03:00
.. _func-range:
.. function:: range(stop)
range(start, stop[, step])
:noindex:
2007-08-15 11:28:22 -03:00
Rather than being a function, :class:`range` is actually an immutable
sequence type, as documented in :ref:`typesseq-range` and :ref:`typesseq`.
2007-08-15 11:28:22 -03:00
.. function:: repr(object)
2008-03-25 04:21:32 -03:00
Return a string containing a printable representation of an object. For many
types, this function makes an attempt to return a string that would yield an
object with the same value when passed to :func:`eval`, otherwise the
representation is a string enclosed in angle brackets that contains the name
of the type of the object together with additional information often
including the name and address of the object. A class can control what this
function returns for its instances by defining a :meth:`__repr__` method.
2007-08-15 11:28:22 -03:00
.. function:: reversed(seq)
Return a reverse :term:`iterator`. *seq* must be an object which has
a :meth:`__reversed__` method or supports the sequence protocol (the
:meth:`__len__` method and the :meth:`__getitem__` method with integer
arguments starting at ``0``).
2007-08-15 11:28:22 -03:00
.. function:: round(number[, ndigits])

Return the floating point value *number* rounded to *ndigits* digits after
the decimal point. If *ndigits* is omitted, it defaults to zero. Delegates
to ``number.__round__(ndigits)``.
2008-07-01 17:39:59 -03:00
For the built-in types supporting :func:`round`, values are rounded to the
closest multiple of 10 to the power minus *ndigits*; if two multiples are
equally close, rounding is done toward the even choice (so, for example,
both ``round(0.5)`` and ``round(-0.5)`` are ``0``, and ``round(1.5)`` is
``2``). The return value is an integer if called with one argument,
otherwise of the same type as *number*.

.. note::
The behavior of :func:`round` for floats can be surprising: for example,
``round(2.675, 2)`` gives ``2.67`` instead of the expected ``2.68``.
This is not a bug: it's a result of the fact that most decimal fractions
can't be represented exactly as a float. See :ref:`tut-fp-issues` for
more information.

.. _func-set:
2007-08-15 11:28:22 -03:00
.. function:: set([iterable])
:noindex:
Return a new :class:`set` object, optionally with elements taken from
*iterable*. ``set`` is a built-in class. See :class:`set` and
:ref:`types-set` for documentation about this class.
For other containers see the built-in :class:`frozenset`, :class:`list`,
:class:`tuple`, and :class:`dict` classes, as well as the :mod:`collections`
module.
2007-08-15 11:28:22 -03:00
.. function:: setattr(object, name, value)
This is the counterpart of :func:`getattr`. The arguments are an object, a
string and an arbitrary value. The string may name an existing attribute or a
new attribute. The function assigns the value to the attribute, provided the
object allows it. For example, ``setattr(x, 'foobar', 123)`` is equivalent to
``x.foobar = 123``.

Return a :term:`slice` object representing the set of indices specified by
2007-08-15 11:28:22 -03:00
``range(start, stop, step)``. The *start* and *step* arguments default to
``None``. Slice objects have read-only data attributes :attr:`~slice.start`,
:attr:`~slice.stop` and :attr:`~slice.step` which merely return the argument
values (or their default). They have no other explicit functionality;
however they are used by Numerical Python and other third party extensions.
Slice objects are also generated when extended indexing syntax is used. For
example: ``a[start:stop:step]`` or ``a[start:stop, i]``. See
:func:`itertools.islice` for an alternate version that returns an iterator.

.. function:: sorted(iterable[, key][, reverse])
2007-08-15 11:28:22 -03:00
Return a new sorted list from the items in *iterable*.
Has two optional arguments which must be specified as keyword arguments.
2007-08-15 11:28:22 -03:00
*key* specifies a function of one argument that is used to extract a comparison
key from each list element: ``key=str.lower``. The default value is ``None``
(compare the elements directly).
2007-08-15 11:28:22 -03:00
*reverse* is a boolean value. If set to ``True``, then the list elements are
sorted as if each comparison were reversed.
2010-08-17 14:52:02 -03:00
Use :func:`functools.cmp_to_key` to convert an old-style *cmp* function to a
*key* function.

2007-12-02 11:22:16 -04:00
The ``@staticmethod`` form is a function :term:`decorator` -- see the
description of function definitions in :ref:`function` for details.
2007-08-15 11:28:22 -03:00
It can be called either on the class (such as ``C.f()``) or on an instance (such
as ``C().f()``). The instance is ignored except for its class.
Static methods in Python are similar to those found in Java or C++. Also see
:func:`classmethod` for a variant that is useful for creating alternate class
constructors.
2007-08-15 11:28:22 -03:00
For more information on static methods, consult the documentation on the
standard type hierarchy in :ref:`types`.
.. index::
single: string; str() (built-in function)
2007-08-15 11:28:22 -03:00
.. _func-str:
.. function:: str(object='')
str(object=b'', encoding='utf-8', errors='strict')
:noindex:
Return a :class:`str` version of *object*. See :func:`str` for details.
``str`` is the built-in string :term:`class`. For general information
about strings, see :ref:`textseq`.
2007-08-15 11:28:22 -03:00
.. function:: sum(iterable[, start])
Sums *start* and the items of an *iterable* from left to right and returns the
total. *start* defaults to ``0``. The *iterable*'s items are normally numbers,
2010-10-31 18:23:24 -03:00
and the start value is not allowed to be a string.
2007-08-15 11:28:22 -03:00
2010-11-06 03:30:16 -03:00
For some use cases, there are good alternatives to :func:`sum`.
2010-10-31 18:23:24 -03:00
The preferred, fast way to concatenate a sequence of strings is by calling
``''.join(sequence)``. To add floating point values with extended precision,
see :func:`math.fsum`\. To concatenate a series of iterables, consider using
:func:`itertools.chain`.
2007-08-15 11:28:22 -03:00
.. function:: super([type[, object-or-type]])
2007-08-15 11:28:22 -03:00
Return a proxy object that delegates method calls to a parent or sibling
class of *type*. This is useful for accessing inherited methods that have
been overridden in a class. The search order is same as that used by
:func:`getattr` except that the *type* itself is skipped.
The :attr:`~class.__mro__` attribute of the *type* lists the method
resolution search order used by both :func:`getattr` and :func:`super`. The
attribute is dynamic and can change whenever the inheritance hierarchy is
updated.

where multiple base classes implement the same method. Good design dictates
that this method have the same calling signature in every case (because the
order of calls is determined at runtime, because that order adapts
to changes in the class hierarchy, and because that order can include
sibling classes that are unknown prior to runtime).

For both use cases, a typical superclass call looks like this::
2007-08-15 11:28:22 -03:00
class C(B):
def method(self, arg):
super().method(arg) # This does the same thing as:
# super(C, self).method(arg)
2007-08-15 11:28:22 -03:00
Note that :func:`super` is implemented as part of the binding process for
explicit dotted attribute lookups such as ``super().__getitem__(name)``.

It does so by implementing its own :meth:`__getattribute__` method for searching
classes in a predictable order that supports cooperative multiple inheritance.
2007-08-15 11:28:22 -03:00
Accordingly, :func:`super` is undefined for implicit lookups using statements or
operators such as ``super()[name]``.
Also note that, aside from the zero argument form, :func:`super` is not
limited to use inside methods. The two argument form specifies the
arguments exactly and makes the appropriate references. The zero
argument form only works inside a class definition, as the compiler fills
in the necessary details to correctly retrieve the class being defined,
as well as accessing the current instance for ordinary methods.
2007-08-15 11:28:22 -03:00
For practical suggestions on how to design cooperative classes using
:func:`super`, see `guide to using super()
<http://rhettinger.wordpress.com/2011/05/26/super-considered-super/>`_.
2007-08-15 11:28:22 -03:00
.. _func-tuple:
2007-08-15 11:28:22 -03:00
.. function:: tuple([iterable])
:noindex:
2007-08-15 11:28:22 -03:00
Rather than being a function, :class:`tuple` is actually an immutable
sequence type, as documented in :ref:`typesseq-tuple` and :ref:`typesseq`.
2007-08-15 11:28:22 -03:00
.. function:: type(object)
type(name, bases, dict)
2007-08-15 11:28:22 -03:00
.. index:: object: type
With one argument, return the type of an *object*. The return value is a
type object and generally the same object as returned by
:attr:`object.__class__ <instance.__class__>`.
The :func:`isinstance` built-in function is recommended for testing the type
of an object, because it takes subclasses into account.
2007-08-15 11:28:22 -03:00
With three arguments, return a new type object. This is essentially a
dynamic form of the :keyword:`class` statement. The *name* string is the
class name and becomes the :attr:`~class.__name__` attribute; the *bases*
tuple itemizes the base classes and becomes the :attr:`~class.__bases__`
attribute; and the *dict* dictionary is the namespace containing definitions
for class body and becomes the :attr:`~object.__dict__` attribute. For
example, the following two statements create identical :class:`type` objects:
2007-08-15 11:28:22 -03:00
>>> class X:
2007-08-15 11:28:22 -03:00
... a = 1
2009-01-03 17:18:54 -04:00
...
2007-08-15 11:28:22 -03:00
>>> X = type('X', (object,), dict(a=1))
See also :ref:`bltin-type-objects`.
2007-08-15 11:28:22 -03:00
.. function:: vars([object])
Return the :attr:`~object.__dict__` attribute for a module, class, instance,
or any other object with a :attr:`__dict__` attribute.

Objects such as modules and instances have an updateable :attr:`__dict__`
attribute; however, other objects may have write restrictions on their
:attr:`__dict__` attributes (for example, classes use a
dictproxy to prevent direct dictionary updates).
Without an argument, :func:`vars` acts like :func:`locals`. Note, the
locals dictionary is only useful for reads since updates to the locals
dictionary are ignored.

2009-01-03 17:18:54 -04:00
Make an iterator that aggregates elements from each of the iterables.
2008-03-12 23:39:40 -03:00
Returns an iterator of tuples, where the *i*-th tuple contains
the *i*-th element from each of the argument sequences or iterables. The
2008-03-12 23:39:40 -03:00
iterator stops when the shortest input iterable is exhausted. With a single
2009-01-03 17:18:54 -04:00
iterable argument, it returns an iterator of 1-tuples. With no arguments,
2008-03-12 23:39:40 -03:00
it returns an empty iterator. Equivalent to::
def zip(*iterables):
# zip('ABCD', 'xy') --> Ax By
sentinel = object()
iterators = [iter(it) for it in iterables]
while iterators:
result = []
for it in iterators:
elem = next(it, sentinel)
if elem is sentinel:
return
result.append(elem)
yield tuple(result)

The left-to-right evaluation order of the iterables is guaranteed. This
makes possible an idiom for clustering a data series into n-length groups
using ``zip(*[iter(s)]*n)``.
2008-03-12 23:39:40 -03:00
:func:`zip` should only be used with unequal length inputs when you don't
care about trailing, unmatched values from the longer iterables. If those
values are important, use :func:`itertools.zip_longest` instead.
2007-08-15 11:28:22 -03:00
2008-10-10 21:49:57 -03:00
:func:`zip` in conjunction with the ``*`` operator can be used to unzip a
list::
>>> x = [1, 2, 3]
>>> y = [4, 5, 6]
>>> zipped = zip(x, y)
2008-12-06 10:28:56 -04:00
>>> list(zipped)
2008-10-10 21:49:57 -03:00
[(1, 4), (2, 5), (3, 6)]
2008-12-06 10:28:56 -04:00
>>> x2, y2 = zip(*zip(x, y))

This function is invoked by the :keyword:`import` statement. It can be
replaced (by importing the :mod:`builtins` module and assigning to
``builtins.__import__``) in order to change semantics of the
:keyword:`import` statement, but doing so is **strongly** discouraged as it
is usually simpler to use import hooks (see :pep:`302`) to attain the same
goals and does not cause issues with code which assumes the default import
implementation is in use. Direct use of :func:`__import__` is also
discouraged in favor of :func:`importlib.import_module`.

The function imports the module *name*, potentially using the given *globals*
and *locals* to determine how to interpret the name in a package context.
The *fromlist* gives the names of objects or submodules that should be
imported from the module given by *name*. The standard implementation does
not use its *locals* argument at all, and uses its *globals* only to
determine the package context of the :keyword:`import` statement.
*level* specifies whether to use absolute or relative imports. ``0`` (the
default) means only perform absolute imports. Positive values for
