:mod:`new` --- Creation of runtime internal objects
|
|
===================================================
|
|
|
|
.. module:: new
|
|
:synopsis: Interface to the creation of runtime implementation objects.
|
|
:deprecated:
|
|
|
|
.. deprecated:: 2.6
|
|
The new module has been removed in Python 3.0.

|
|
|
The :mod:`new` module allows an interface to the interpreter object creation
|
|
functions. This is for use primarily in marshal-type functions, when a new
|
|
object needs to be created "magically" and not by using the regular creation
|
|
functions. This module provides a low-level interface to the interpreter, so
|
|
care must be exercised when using this module. It is possible to supply
|
|
non-sensical arguments which crash the interpreter when the object is used.
|
|
|
|
The :mod:`new` module defines the following functions:
|
|
|
|
|
|
.. function:: instance(class[, dict])
|
|
|
|
This function creates an instance of *class* with dictionary *dict* without
|
|
calling the :meth:`__init__` constructor. If *dict* is omitted or ``None``, a
|
|
new, empty dictionary is created for the new instance. Note that there are no
|
|
guarantees that the object will be in a consistent state.
|
|
|
|
|
|
.. function:: instancemethod(function, instance, class)
|
|
|
|
This function will return a method object, bound to *instance*, or unbound if
|
|
*instance* is ``None``. *function* must be callable.
|
|
|
|
|
|
.. function:: function(code, globals[, name[, argdefs[, closure]]])
|
|
|
|
Returns a (Python) function with the given code and globals. If *name* is given,
|
|
it must be a string or ``None``. If it is a string, the function will have the
|
|
given name, otherwise the function name will be taken from ``code.co_name``. If
|
|
*argdefs* is given, it must be a tuple and will be used to determine the default
|
|
values of parameters. If *closure* is given, it must be ``None`` or a tuple of
|
|
cell objects containing objects to bind to the names in ``code.co_freevars``.
|
|
|
|
|
|
.. function:: code(argcount, nlocals, stacksize, flags, codestring, constants, names, varnames, filename, name, firstlineno, lnotab)
|
|
|
|
This function is an interface to the :cfunc:`PyCode_New` C function.
|
|
|
|
.. XXX This is still undocumented!
|
|
|
|
|
|
.. function:: module(name[, doc])
|
|
|
|
This function returns a new module object with name *name*. *name* must be a
|
|
string. The optional *doc* argument can have any type.
|
|
|
|
|
|
.. function:: classobj(name, baseclasses, dict)
|
|
|
|
This function returns a new class object, with name *name*, derived from
|
|
*baseclasses* (which should be a tuple of classes) and with namespace *dict*.
