This value is not actually defined by the module, but can be set by the user (or by a program) to specify a clean-up action at program exit. When set, it should be a parameterless function. This function - will be called when the interpreter exits. Note: the exit function + will be called when the interpreter exits. Only one function may be + installed in this way; to allow multiple functions which will be called + at termination, use the \refmodule{atexit} module. Note: the exit function is not called when the program is killed by a signal, when a Python fatal internal error is detected, or when \code{os._exit()} is called. \end{datadesc} |
