6 :synopsis: Interface to the creation of runtime implementation objects. |

|
10 The :mod:`new` module has been removed in Python 3.0. |

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. |
|
21 |
|
22 The :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*. |
