5.16 new -- Creation of runtime internal objects

5.16 new -- Creation of runtime internal objects

The 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 new module defines the following functions:

instance( class[, dict])
This function creates an instance of class with dictionary dict without calling the __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.

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( 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.

code( argcount, nlocals, stacksize, flags, codestring, constants, names, varnames, filename, name, firstlineno, lnotab)
This function is an interface to the PyCode_New() C 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.

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.
