Minor fix-ups to named tuples:
* Make the _replace() method respect subclassing.
* Using property() to make _fields read-only wasn't a good idea.
It caused len(Point._fields) to fail.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

Expression statements are used (mostly interactively) to compute and write a
|
|
|
|
value, or (usually) to call a procedure (a function that returns no meaningful
|
|
|
|
result; in Python, procedures return the value ``None``). Other uses of
|
|
|
|
expression statements are allowed and occasionally useful. The syntax for an
|
|
|
|
expression statement is:

|
|

expression_stmt: `starred_expression`
|
2007-08-15 11:28:22 -03:00
|
|
|
|
|
|
|
An expression statement evaluates the expression list (which may be a single
|
|
|
|
expression).
|
|
|
|
|
|
|
|
.. index::
|
|
|
|
builtin: repr
|
|
|
|
object: None
|
|
|
|
pair: string; conversion
|
|
|
|
single: output
|
|
|
|
pair: standard; output
|
|
|
|
pair: writing; values
|
|
|
|
pair: procedure; call
|
|
|
|
|
|
|
|
In interactive mode, if the value is not ``None``, it is converted to a string
|
|
|
|
using the built-in :func:`repr` function and the resulting string is written to
|
2007-09-07 14:52:53 -03:00
|
|
|
standard output on a line by itself (except if the result is ``None``, so that
|
|
|
|
procedure calls do not cause any output.)

|
2007-08-15 11:28:22 -03:00
|
|
|
|
|
|
|
An assignment statement evaluates the expression list (remember that this can be
|
|
|
|
a single expression or a comma-separated list, the latter yielding a tuple) and
|
|
|
|
assigns the single resulting object to each of the target lists, from left to
|
|
|
|
right.
|
|
|
|
|
|
|
|
.. index::
|
|
|
|
single: target
|
|
|
|
pair: target; list
|
|
|
|
|
|
|
|
Assignment is defined recursively depending on the form of the target (list).
|
|
|
|
When a target is part of a mutable object (an attribute reference, subscription
|
|
|
|
or slicing), the mutable object must ultimately perform the assignment and
|
|
|
|
decide about its validity, and may raise an exception if the assignment is
|
|
|
|
unacceptable. The rules observed by various types and the exceptions raised are
|
|
|
|
given with the definition of the object types (see section :ref:`types`).

Assignment of an object to a target list, optionally enclosed in parentheses or
|
|
|
|
square brackets, is recursively defined as follows.
|
2007-08-15 11:28:22 -03:00
|
|
|
|
2018-11-11 19:59:39 -04:00

|
* If the target list is a single target with no trailing comma,
|
|
|
|
optionally in parentheses, the object is assigned to that target.

|
|
|
|
2018-11-11 19:59:39 -04:00
|
|
|
* Else: The object must be an iterable with the same number of
|
2016-05-18 02:44:29 -03:00
|
|
|
items as there are targets in the target list, and the items are assigned,
|
|
|
|
from left to right, to the corresponding targets.

|

|
"starred" target: The object must be an iterable with at least as many items
|
2007-09-07 14:52:53 -03:00
|
|
|
as there are targets in the target list, minus one. The first items of the
|
2016-05-18 02:44:29 -03:00
|
|
|
iterable are assigned, from left to right, to the targets before the starred
|
|
|
|
target. The final items of the iterable are assigned to the targets after
|
|
|
|
the starred target. A list of the remaining items in the iterable is then
|
2007-09-07 14:52:53 -03:00
|
|
|
assigned to the starred target (the list can be empty).

Assignment of an object to a single target is recursively defined as follows.
|
2007-08-15 11:28:22 -03:00
|
|
|
|
2007-09-07 14:52:53 -03:00

|
2007-09-07 14:52:53 -03:00
|
|
|
* If the name does not occur in a :keyword:`global` or :keyword:`nonlocal`

The name is rebound if it was already bound. This may cause the reference
|
|
|
|
count for the object previously bound to the name to reach zero, causing the
|
|
|
|
object to be deallocated and its destructor (if it has one) to be called.

2019-05-03 11:59:05 -03:00
|

both sides of the assignment operator, the right-hand side expression, ``a.x`` can access

2009-09-16 13:00:31 -03:00

either an instance attribute or (if no instance attribute exists) a class

2019-05-03 11:59:05 -03:00

attribute. The left-hand side target ``a.x`` is always set as an instance attribute,
|
2009-09-16 13:00:31 -03:00

|
creating it if necessary. Thus, the two occurrences of ``a.x`` do not
|
2019-05-03 11:59:05 -03:00
|
|
|
necessarily refer to the same attribute: if the right-hand side expression refers to a

class attribute, the left-hand side creates a new instance attribute as the target of the

|
|
* If the target is a subscription: The primary expression in the reference is
|
2007-09-07 14:52:53 -03:00
|
|
|
evaluated. It should yield either a mutable sequence object (such as a list)
|
|
|
|
or a mapping object (such as a dictionary). Next, the subscript expression is
|
2007-08-15 11:28:22 -03:00
|
|
|
evaluated.

If the primary is a mutable sequence object (such as a list), the subscript
|
|
|
|
must yield an integer. If it is negative, the sequence's length is added to
|
|
|
|
it. The resulting value must be a nonnegative integer less than the
|
|
|
|
sequence's length, and the sequence is asked to assign the assigned object to
|
|
|
|
its item with that index. If the index is out of range, :exc:`IndexError` is
|
|
|
|
raised (assignment to a subscripted sequence cannot add new items to a list).

If the primary is a mapping object (such as a dictionary), the subscript must

|

have a type compatible with the mapping's key type, and the mapping is then
|
|
|
|
asked to create a key/datum pair which maps the subscript to the assigned
|
|
|
|
object. This can either replace an existing key/value pair with the same key
|
|
|
|
value, or insert a new key/value pair (if no key with the same value existed).

|
|
|
|
|
|
* If the target is a slicing: The primary expression in the reference is
|
|
|
|
evaluated. It should yield a mutable sequence object (such as a list). The
|
|
|
|
assigned object should be a sequence object of the same type. Next, the lower
|
|
|
|
and upper bound expressions are evaluated, insofar they are present; defaults
|
2007-09-07 14:52:53 -03:00
|
|
|
are zero and the sequence's length. The bounds should evaluate to integers.
|
|
|
|
If either bound is negative, the sequence's length is added to it. The
|
|
|
|
resulting bounds are clipped to lie between zero and the sequence's length,
|
|
|
|
inclusive. Finally, the sequence object is asked to replace the slice with
|
|
|
|
the items of the assigned sequence. The length of the slice may be different
|
|
|
|
from the length of the assigned sequence, thus changing the length of the
|
2014-05-27 02:20:37 -03:00
|
|
|
target sequence, if the target sequence allows it.

|
|
|
In the current implementation, the syntax for targets is taken to be the same
|
|
|
|
as for expressions, and invalid syntax is rejected during the code generation
|
|
|
|
phase, causing less detailed error messages.

Although the definition of assignment implies that overlaps between the
|
2016-05-08 10:48:10 -03:00
|
|
|
left-hand side and the right-hand side are 'simultaneous' (for example ``a, b =
|
2014-05-27 02:20:37 -03:00
|
|
|
b, a`` swaps two variables), overlaps *within* the collection of assigned-to
|
|
|
|
variables occur left-to-right, sometimes resulting in confusion. For instance,
|
|
|
|
the following program prints ``[0, 2]``::

|
An augmented assignment evaluates the target (which, unlike normal assignment
|
|
|
|
statements, cannot be an unpacking) and the expression list, performs the binary
|
|
|
|
operation specific to the type of assignment on the two operands, and assigns
|
|
|
|
the result to the original target. The target is only evaluated once.
|
|
|
|
|
|
|
|
An augmented assignment expression like ``x += 1`` can be rewritten as ``x = x +
|
|
|
|
1`` to achieve a similar, but not exactly equal effect. In the augmented
|
|
|
|
version, ``x`` is only evaluated once. Also, when possible, the actual operation
|
|
|
|
is performed *in-place*, meaning that rather than creating a new object and
|
|
|
|
assigning that to the target, the old object is modified instead.
|
|
|
|
|
2014-05-27 02:20:37 -03:00
|
|
|
Unlike normal assignments, augmented assignments evaluate the left-hand side
|
|
|
|
*before* evaluating the right-hand side. For example, ``a[i] += f(x)`` first
|
|
|
|
looks-up ``a[i]``, then it evaluates ``f(x)`` and performs the addition, and
|
|
|
|
lastly, it writes the result back to ``a[i]``.
|
|
|
|
|
2007-08-15 11:28:22 -03:00
|
|
|
With the exception of assigning to tuples and multiple targets in a single
|
|
|
|
statement, the assignment done by augmented assignment statements is handled the
|
|
|
|
same way as normal assignments. Similarly, with the exception of the possible
|
|
|
|
*in-place* behavior, the binary operation performed by augmented assignment is
|
|
|
|
the same as the normal binary operations.
|
|
|
|
|
2009-09-16 13:00:31 -03:00
|
|
|
For targets which are attribute references, the same :ref:`caveat about class
|
|
|
|
and instance attributes <attr-target-note>` applies as for regular assignments.

:term:`Annotation <variable annotation>` assignment is the combination, in a single

The difference from normal :ref:`assignment` is that only single target is allowed.
|
2016-09-09 00:50:03 -03:00
|
|
|
|
|
|
|
For simple names as assignment targets, if in class or module scope,
|
|
|
|
the annotations are evaluated and stored in a special class or module
|
|
|
|
attribute :attr:`__annotations__`
|
2016-09-11 13:45:24 -03:00
|
|
|
that is a dictionary mapping from variable names (mangled if private) to
|
|
|
|
evaluated annotations. This attribute is writable and is automatically
|
|
|
|
created at the start of class or module body execution, if annotations
|
|
|
|
are found statically.
|
2016-09-09 00:50:03 -03:00
|
|
|
|
|
|
|
For expressions as assignment targets, the annotations are evaluated if
|
|
|
|
in class or module scope, but not stored.
|
|
|
|
|
|
|
|
If a name is annotated in a function scope, then this name is local for
|
|
|
|
that scope. Annotations are never evaluated and stored in function scopes.
|
|
|
|
|
|
|
|
If the right hand side is present, an annotated
|
|
|
|
assignment performs the actual assignment before evaluating annotations
|
|
|
|
(where applicable). If the right hand side is not present for an expression
|
|
|
|
target, then the interpreter evaluates the target except for the last
|
|
|
|
:meth:`__setitem__` or :meth:`__setattr__` call.

:pep:`526` - Syntax for Variable Annotations
|
|
|
|
The proposal that added syntax for annotating the types of variables
|
|
|
|
(including class variables and instance variables), instead of expressing
|
|
|
|
them through comments.

|

|
|
|
|
syntax for type annotations that can be used in static analysis tools and
|
|
|
|
IDEs.

.. versionchanged:: 3.8
|
|
|
|
Now annotated assignments allow same expressions in the right hand side as
|
2019-06-04 07:37:46 -03:00
|
|
|
the regular assignments. Previously, some expressions (like un-parenthesized
|
2019-06-02 20:41:00 -03:00
|
|
|
tuple expressions) caused a syntax error.

Patch # 1140 (my code, approved by Effbot).
Make sure the type of the return value of re.sub(x, y, z) is the type
of y+x (i.e. unicode if either is unicode, str if they are both str)
even if there are no substitutions or if x==z (which triggered various
special cases in join_list()).
Could be backported to 2.5; no need to port to 3.0.

Patch # 1140 (my code, approved by Effbot).
Make sure the type of the return value of re.sub(x, y, z) is the type
of y+x (i.e. unicode if either is unicode, str if they are both str)
even if there are no substitutions or if x==z (which triggered various
special cases in join_list()).
Could be backported to 2.5; no need to port to 3.0.

same.

Patch # 1140 (my code, approved by Effbot).
Make sure the type of the return value of re.sub(x, y, z) is the type
of y+x (i.e. unicode if either is unicode, str if they are both str)
even if there are no substitutions or if x==z (which triggered various
special cases in join_list()).
Could be backported to 2.5; no need to port to 3.0.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

:keyword:`pass` is a null operation --- when it is executed, nothing happens.

It is useful as a placeholder when a statement is required syntactically, but no

|
|
|
|
|
|
|
|
def f(arg): pass # a function that does nothing (yet)
|
|

|
|
|
|

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

Deletion is recursively defined very similar to the way assignment is defined.

Rather than spelling it out in full details, here are some hints.
|
2007-08-15 11:28:22 -03:00
|

|
|

Deletion of a target list recursively deletes each target, from left to right.

|

2007-09-07 14:52:53 -03:00
|
|
|
Deletion of a name removes the binding of that name from the local or global
|
2007-08-15 11:28:22 -03:00
|
|
|
namespace, depending on whether the name occurs in a :keyword:`global` statement
|
|
|
|
in the same code block. If the name is unbound, a :exc:`NameError` exception
|
|
|
|
will be raised.
|
|
|
|
|
|
|
|
.. index:: pair: attribute; deletion
|
|
|
|
|
|
|
|
Deletion of attribute references, subscriptions and slicings is passed to the
|
|
|
|
primary object involved; deletion of a slicing is in general equivalent to
|
|
|
|
assignment of an empty slice of the right type (but even this is determined by
|
|
|
|
the sliced object).

occurs as a free variable in a nested block.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

return_stmt: "return" [`expression_list`]
|
|
|
|
|
|
|
|
:keyword:`return` may only occur syntactically nested in a function definition,
|
|
|
|
not within a nested class definition.
|
|
|
|
|
|
|
|
If an expression list is present, it is evaluated, else ``None`` is substituted.
|
|
|
|
|
|
|
|
:keyword:`return` leaves the current function call with the expression list (or
|
|
|
|
``None``) as return value.

When :keyword:`return` passes control out of a :keyword:`try` statement with a
|
2018-12-19 02:09:46 -04:00
|
|
|
:keyword:`finally` clause, that :keyword:`!finally` clause is executed before
|
2007-08-15 11:28:22 -03:00
|
|
|
really leaving the function.
|
|
|
|
|
2012-01-13 07:43:40 -04:00
|
|
|
In a generator function, the :keyword:`return` statement indicates that the
|
|
|
|
generator is done and will cause :exc:`StopIteration` to be raised. The returned
|
|
|
|
value (if any) is used as an argument to construct :exc:`StopIteration` and
|
|
|
|
becomes the :attr:`StopIteration.value` attribute.

In an asynchronous generator function, an empty :keyword:`return` statement
|
|
|
|
indicates that the asynchronous generator is done and will cause
|
2018-12-19 02:09:46 -04:00
|
|
|
:exc:`StopAsyncIteration` to be raised. A non-empty :keyword:`!return`
|
2016-12-15 18:36:05 -04:00
|
|
|
statement is a syntax error in an asynchronous generator function.

Minor fix-ups to named tuples:
* Make the _replace() method respect subclassing.
* Using property() to make _fields read-only wasn't a good idea.
It caused len(Point._fields) to fail.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

Re-implement the 'warnings' module in C. This allows for usage of the
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.

Re-implement the 'warnings' module in C. This allows for usage of the
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.
Closes issue #1631171.

Yield expressions and statements are only used when defining a :term:`generator`
|
|
|
|
function, and are only used in the body of the generator function. Using yield
|
|
|
|
in a function definition is sufficient to cause that definition to create a
|
|
|
|
generator function instead of a normal function.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

|
|
If no expressions are present, :keyword:`raise` re-raises the last exception
|
|
|
|
that was active in the current scope. If no exception is active in the current
|
2012-01-01 07:17:15 -04:00
|
|
|
scope, a :exc:`RuntimeError` exception is raised indicating that this is an
|
|
|
|
error.
|
2007-08-15 11:28:22 -03:00
|
|
|
|
2007-09-07 14:52:53 -03:00
|
|
|
Otherwise, :keyword:`raise` evaluates the first expression as the exception
|
|
|
|
object. It must be either a subclass or an instance of :class:`BaseException`.
|
|
|
|
If it is a class, the exception instance will be obtained when needed by
|
|
|
|
instantiating the class with no arguments.
|

|
|
|
|
2007-09-07 14:52:53 -03:00
|
|
|
The :dfn:`type` of the exception is the exception instance's class, the
|
|
|
|
:dfn:`value` is the instance itself.

.. index:: object: traceback
|
|
|
|
|
2007-09-07 14:52:53 -03:00
|
|
|
A traceback object is normally created automatically when an exception is raised
|
2008-05-05 18:42:51 -03:00
|
|
|
and attached to it as the :attr:`__traceback__` attribute, which is writable.
|
|
|
|
You can create an exception and set your own traceback in one step using the
|
|
|
|
:meth:`with_traceback` exception method (which returns the same exception
|
|
|
|
instance, with its traceback set to its argument), like so::
|
2007-09-07 14:52:53 -03:00
|
|
|
|
2009-02-16 12:15:34 -04:00
|
|
|
raise Exception("foo occurred").with_traceback(tracebackobj)
|
2007-09-07 14:52:53 -03:00

|
|
|

2008-07-19 12:51:07 -03:00
|
|
|
The ``from`` clause is used for exception chaining: if given, the second
|
2021-04-11 05:33:59 -03:00
|
|
|
*expression* must be another exception class or instance. If the second
|
|
|
|
expression is an exception instance, it will be attached to the raised
|
|
|
|
exception as the :attr:`__cause__` attribute (which is writable). If the
|
|
|
|
expression is an exception class, the class will be instantiated and the
|
|
|
|
resulting exception instance will be attached to the raised exception as the
|
|
|
|
:attr:`__cause__` attribute. If the raised exception is not handled, both
|
|
|
|
exceptions will be printed::
|

|
|
|
exception handler or a :keyword:`finally` clause: the previous exception is then

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

* Make the _replace() method respect subclassing.

|
|
The basic import statement (no :keyword:`from` clause) is executed in two
|
|
|
|
steps:
|
|
|
|
|
|
|
|
#. find a module, loading and initializing it if necessary
|
|
|
|
#. define a name or names in the local namespace for the scope where
|
|
|
|
the :keyword:`import` statement occurs.
|
|
|
|
|
|
|
|
When the statement contains multiple clauses (separated by
|
|
|
|
commas) the two steps are carried out separately for each clause, just
|
2016-05-17 22:44:46 -03:00
|
|
|
as though the clauses had been separated out into individual import
|
2012-08-02 09:02:35 -03:00
|
|
|
statements.
|
|
|
|
|
2014-05-27 02:20:37 -03:00
|
|
|
The details of the first step, finding and loading modules are described in
|
2012-08-02 09:02:35 -03:00
|
|
|
greater detail in the section on the :ref:`import system <importsystem>`,
|
|
|
|
which also describes the various types of packages and modules that can
|
|
|
|
be imported, as well as all the hooks that can be used to customize
|
|
|
|
the import system. Note that failures in this step may indicate either
|
|
|
|
that the module could not be located, *or* that an error occurred while
|
|
|
|
initializing the module, which includes execution of the module's code.
|
|
|
|
|
|
|
|
If the requested module is retrieved successfully, it will be made
|
|
|
|
available in the local namespace in one of three ways:
|
|
|
|
|
2014-04-29 01:58:56 -03:00
|
|
|
.. index:: single: as; import statement
|
|
|
|
|
2018-12-19 02:09:46 -04:00
|
|
|
* If the module name is followed by :keyword:`!as`, then the name
|
|
|
|
following :keyword:`!as` is bound directly to the imported module.
|
2012-08-02 09:02:35 -03:00
|
|
|
* If no other name is specified, and the module being imported is a top
|
|
|
|
level module, the module's name is bound in the local namespace as a
|
|
|
|
reference to the imported module
|
|
|
|
* If the module being imported is *not* a top level module, then the name
|
|
|
|
of the top level package that contains the module is bound in the local
|
|
|
|
namespace as a reference to the top level package. The imported module
|
|
|
|
must be accessed using its full qualified name rather than directly
|
2012-07-31 17:03:09 -03:00
|
|
|
|
2007-08-15 11:28:22 -03:00

|
|
|
|
2012-08-02 09:02:35 -03:00
|
|
|
The :keyword:`from` form uses a slightly more complex process:
|
|
|
|
|
2014-05-27 02:20:37 -03:00
|
|
|
#. find the module specified in the :keyword:`from` clause, loading and
|
2012-08-02 09:02:35 -03:00
|
|
|
initializing it if necessary;
|
|
|
|
#. for each of the identifiers specified in the :keyword:`import` clauses:
|
|
|
|
|
|
|
|
#. check if the imported module has an attribute by that name
|
|
|
|
#. if not, attempt to import a submodule with that name and then
|
|
|
|
check the imported module again for that attribute
|
|
|
|
#. if the attribute is not found, :exc:`ImportError` is raised.
|
2014-05-27 02:20:37 -03:00
|
|
|
#. otherwise, a reference to that value is stored in the local namespace,
|
2018-12-19 02:09:46 -04:00
|
|
|
using the name in the :keyword:`!as` clause if it is present,
|
2012-08-02 09:02:35 -03:00
|
|
|
otherwise using the attribute name
|
|
|
|
|
|
|
|
Examples::
|
|
|
|
|
|
|
|
import foo # foo imported and bound locally
|
|
|
|
import foo.bar.baz # foo.bar.baz imported, foo bound locally
|
|
|
|
import foo.bar.baz as fbb # foo.bar.baz imported and bound as fbb
|
|
|
|
from foo.bar import baz # foo.bar.baz imported and bound as baz
|
|
|
|
from foo import attr # foo imported and foo.attr bound as attr
|
|
|
|
|
2018-10-28 08:41:26 -03:00
|
|
|
.. index:: single: * (asterisk); import statement
|
2018-10-26 03:00:49 -03:00
|
|
|
|
2012-08-02 09:02:35 -03:00
|
|
|
If the list of identifiers is replaced by a star (``'*'``), all public
|
|
|
|
names defined in the module are bound in the local namespace for the scope
|
|
|
|
where the :keyword:`import` statement occurs.
|
|
|
|
|
|
|
|
.. index:: single: __all__ (optional module attribute)
|
|
|
|
|
|
|
|
The *public names* defined by a module are determined by checking the module's
|
|
|
|
namespace for a variable named ``__all__``; if defined, it must be a sequence
|
|
|
|
of strings which are names defined or imported by that module. The names
|
2012-07-29 17:36:17 -03:00
|
|
|
given in ``__all__`` are all considered public and are required to exist. If
|
|
|
|
``__all__`` is not defined, the set of public names includes all names found
|
|
|
|
in the module's namespace which do not begin with an underscore character
|
|
|
|
(``'_'``). ``__all__`` should contain the entire public API. It is intended
|
|
|
|
to avoid accidentally exporting items that are not part of the API (such as
|
|
|
|
library modules which were imported and used within the module).
|

|
|
|
|
2014-10-31 06:38:49 -03:00
|
|
|
The wild card form of import --- ``from module import *`` --- is only allowed at
|
|
|
|
the module level. Attempting to use it in class or function definitions will
|
|
|
|
raise a :exc:`SyntaxError`.
|
2007-08-15 11:28:22 -03:00
|
|
|
|
|
|
|
.. index::
|
2009-03-21 00:11:16 -03:00
|
|
|
single: relative; import
|
|
|
|
|
|
|
|
When specifying what module to import you do not have to specify the absolute
|
|
|
|
name of the module. When a module or package is contained within another
|
|
|
|
package it is possible to make a relative import within the same top package
|
|
|
|
without having to mention the package name. By using leading dots in the
|
|
|
|
specified module or package after :keyword:`from` you can specify how high to
|
|
|
|
traverse up the current package hierarchy without specifying exact names. One
|
|
|
|
leading dot means the current package where the module making the import
|
|
|
|
exists. Two dots means up one package level. Three dots is up two levels, etc.
|
|
|
|
So if you execute ``from . import mod`` from a module in the ``pkg`` package
|
|
|
|
then you will end up importing ``pkg.mod``. If you execute ``from ..subpkg2
|
2010-09-03 17:23:40 -03:00
|
|
|
import mod`` from within ``pkg.subpkg1`` you will import ``pkg.subpkg2.mod``.
|
2019-04-24 12:14:44 -03:00
|
|
|
The specification for relative imports is contained in
|
|
|
|
the :ref:`relativeimports` section.

|
|
|
|
|
|
|
A :dfn:`future statement` is a directive to the compiler that a particular
|
|
|
|
module should be compiled using syntax or semantics that will be available in a
|
2014-05-27 02:20:37 -03:00
|
|
|
specified future release of Python where the feature becomes standard.
|
|
|
|
|
|
|
|
The future statement is intended to ease migration to future versions of Python
|
|
|
|
that introduce incompatible changes to the language. It allows use of the new
|
|
|
|
features on a per-module basis before the release in which the feature becomes
|
|
|
|
standard.

|
2007-08-15 11:28:22 -03:00
|
|
|
|
|
|
|
A future statement must appear near the top of the module. The only lines that
|
|
|
|
can appear before a future statement are:
|
|
|
|
|
|
|
|
* the module docstring (if any),
|
|
|
|
* comments,
|
|
|
|
* blank lines, and
|
|
|
|
* other future statements.
|
|
|
|
|
2021-04-21 08:41:19 -03:00
|
|
|
The only feature that requires using the future statement is
|
|
|
|
``annotations`` (see :pep:`563`).
|
|
|
|
|
2018-01-26 12:20:18 -04:00
|
|
|
All historical features enabled by the future statement are still recognized
|
|
|
|
by Python 3. The list includes ``absolute_import``, ``division``,
|
|
|
|
``generators``, ``generator_stop``, ``unicode_literals``,
|
2021-04-21 08:41:19 -03:00
|
|
|
``print_function``, ``nested_scopes`` and ``with_statement``. They are
|
|
|
|
all redundant because they are always enabled, and only kept for
|
2018-01-26 12:20:18 -04:00
|
|
|
backwards compatibility.
|
2007-08-15 11:28:22 -03:00
|
|
|
|
|
|
|
A future statement is recognized and treated specially at compile time: Changes
|
|
|
|
to the semantics of core constructs are often implemented by generating
|
|
|
|
different code. It may even be the case that a new feature introduces new
|
|
|
|
incompatible syntax (such as a new reserved word), in which case the compiler
|
|
|
|
may need to parse the module differently. Such decisions cannot be pushed off
|
|
|
|
until runtime.
|
|
|
|
|
|
|
|
For any given release, the compiler knows which feature names have been defined,
|
|
|
|
and raises a compile-time error if a future statement contains a feature not
|
|
|
|
known to it.
|
|
|
|
|
|
|
|
The direct runtime semantics are the same as for any import statement: there is
|
|
|
|
a standard module :mod:`__future__`, described later, and it will be imported in
|
|
|
|
the usual way at the time the future statement is executed.
|
|
|
|
|
|
|
|
The interesting runtime semantics depend on the specific feature enabled by the
|
|
|
|
future statement.
|
|
|
|
|
|
|
|
Note that there is nothing special about the statement::
|
|
|
|
|
|
|
|
import __future__ [as name]
|
|
|
|
|
|
|
|
That is not a future statement; it's an ordinary import statement with no
|
|
|
|
special semantics or syntax restrictions.
|
|
|
|
|
2009-07-26 11:54:51 -03:00
|
|
|
Code compiled by calls to the built-in functions :func:`exec` and :func:`compile`
|
2007-09-07 14:52:53 -03:00
|
|
|
that occur in a module :mod:`M` containing a future statement will, by default,
|
|
|
|
use the new syntax or semantics associated with the future statement. This can
|
|
|
|
be controlled by optional arguments to :func:`compile` --- see the documentation
|
|
|
|
of that function for details.
|
2007-08-15 11:28:22 -03:00
|
|
|
|
|
|
|
A future statement typed at an interactive interpreter prompt will take effect
|
|
|
|
for the rest of the interpreter session. If an interpreter is started with the
|
|
|
|
:option:`-i` option, is passed a script name to execute, and the script includes
|
|
|
|
a future statement, it will be in effect in the interactive session started
|
|
|
|
after the script is executed.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

Minor fix-ups to named tuples:
* Make the _replace() method respect subclassing.
* Using property() to make _fields read-only wasn't a good idea.
It caused len(Point._fields) to fail.
* Add note to _cast() about length checking and alternative with the star-operator.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.

**Programmer's note:** :keyword:`global` is a directive to the parser. It
|
2018-12-19 02:09:46 -04:00
|
|
|
applies only to code parsed at the same time as the :keyword:`!global` statement.
|
|
|
|
In particular, a :keyword:`!global` statement contained in a string or code
|
2010-02-06 14:46:57 -04:00
|
|
|
object supplied to the built-in :func:`exec` function does not affect the code

|
2007-08-15 11:28:22 -03:00

call. The same applies to the :func:`eval` and :func:`compile` functions.

The :keyword:`nonlocal` statement causes the listed identifiers to refer to
|
2014-05-27 02:20:37 -03:00
|
|
|
previously bound variables in the nearest enclosing scope excluding globals.
|
|
|
|
This is important because the default behavior for binding is to search the
|
|
|
|
local namespace first. The statement allows encapsulated code to rebind
|
|
|
|
variables outside of the local scope besides the global (module) scope.

.. XXX not implemented
|

|
The :keyword:`nonlocal` statement may prepend an assignment or augmented
|
|
|
|
assignment, but not an expression.

Names listed in a :keyword:`nonlocal` statement, unlike those listed in a
|
2007-12-04 14:11:03 -04:00
|
|
|
:keyword:`global` statement, must refer to pre-existing bindings in an
|
|
|
|
enclosing scope (the scope in which a new binding should be created cannot
|
|
|
|
be determined unambiguously).
|
|
|
|
|
2009-01-03 17:18:54 -04:00
|
|
|
Names listed in a :keyword:`nonlocal` statement must not collide with
|
2007-12-04 14:11:03 -04:00
|
|
|
pre-existing bindings in the local scope.
