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*. + |
