The atexit Module

(2.0 only) The atexit module allows you to register one or more functions that are called when the interpreter is terminated.

To register a function, simply call the register function, as shown in Example 1-78. You can also add one or more extra arguments, which are passed as arguments to the exit function.

Example 1-78. Using the atexit Module

File: atexit-example-1.py import atexit def exit(*args): print "exit", args # register two exit handler atexit.register(exit) atexit.register(exit, 1) atexit.register(exit, "hello", "world") exit ('hello', 'world') exit (1,) exit ()

This module is a straightforward wrapper for the sys.exitfunc hook.
