 8.. deprecated:: 2.6
 9   The :mod:`new` module has been removed in Python 3.0.  Use the :mod:`types`
10   module's classes instead.

15The :mod:`new` module allows an interface to the interpreter object creation
16functions. This is for use primarily in marshal-type functions, when a new
17object needs to be created "magically" and not by using the regular creation
18functions. This module provides a low-level interface to the interpreter, so
19care must be exercised when using this module. It is possible to supply
20non-sensical arguments which crash the interpreter when the object is used.
21
22The :mod:`new` module defines the following functions:
23
24
25.. function:: instance(class[, dict])
26
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.
31
32
33.. function:: instancemethod(function, instance, class)
34
35   This function will return a method object, bound to *instance*, or unbound if
36   *instance* is ``None``.  *function* must be callable.
37
38
39.. function:: function(code, globals[, name[, argdefs[, closure]]])
40
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``.
47
48
49.. function:: code(argcount, nlocals, stacksize, flags, codestring, constants, names, varnames, filename, name, firstlineno, lnotab)
50
51   This function is an interface to the :cfunc:`PyCode_New` C function.
52
53   .. XXX This is still undocumented!
54
55
56.. function:: module(name[, doc])
57
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.
60
61
62.. function:: classobj(name, baseclasses, dict)
63
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*.
