1 :mod:`new` --- Creation of runtime internal objects
2 ===================================================
5 :synopsis: Interface to the creation of runtime implementation objects.
9 The :mod:`new` module has been removed in Python 3.0. Use the :mod:`types`
10 module's classes instead.
12 .. sectionauthor:: Moshe Zadka <moshez@zadka.site.co.il>
15 The :mod:`new` module allows an interface to the interpreter object creation
16 functions. This is for use primarily in marshal-type functions, when a new
17 object needs to be created "magically" and not by using the regular creation
18 functions. This module provides a low-level interface to the interpreter, so
19 care must be exercised when using this module. It is possible to supply
20 non-sensical arguments which crash the interpreter when the object is used.
22 The :mod:`new` module defines the following functions:
25 .. function:: instance(class[, dict])
27 This function creates an instance of *class* with dictionary *dict* without
28 calling the :meth:`__init__` constructor. If *dict* is omitted or ``None``, a
29 new, empty dictionary is created for the new instance. Note that there are no
30 guarantees that the object will be in a consistent state.
33 .. function:: instancemethod(function, instance, class)
35 This function will return a method object, bound to *instance*, or unbound if
36 *instance* is ``None``. *function* must be callable.
39 .. function:: function(code, globals[, name[, argdefs[, closure]]])
41 Returns a (Python) function with the given code and globals. If *name* is given,
42 it must be a string or ``None``. If it is a string, the function will have the
43 given name, otherwise the function name will be taken from ``code.co_name``. If
44 *argdefs* is given, it must be a tuple and will be used to determine the default
45 values of parameters. If *closure* is given, it must be ``None`` or a tuple of
46 cell objects containing objects to bind to the names in ``code.co_freevars``.
49 .. function:: code(argcount, nlocals, stacksize, flags, codestring, constants, names, varnames, filename, name, firstlineno, lnotab)
51 This function is an interface to the :cfunc:`PyCode_New` C function.
53 .. XXX This is still undocumented!
56 .. function:: module(name[, doc])
58 This function returns a new module object with name *name*. *name* must be a
59 string. The optional *doc* argument can have any type.
62 .. function:: classobj(name, baseclasses, dict)
64 This function returns a new class object, with name *name*, derived from
65 *baseclasses* (which should be a tuple of classes) and with namespace *dict*.
