Python: call function on any kind of termination

Question

From reading documentation and other questions here, I see different examples for how to execute functions on SIGINT, SIGTERM, on calls to sys.exit(), etc.

Is there any way to register a function to run on any kind of termination? "any kind" means:

Regular exit using sys.exit() or when the flow ends
An uncaught error that crashes the application
External various killing signals

Note: The functions registered via this module are **not** called when the program is killed by a signal not handled by Python, when a Python fatal internal error is detected, or when os._exit() is called. — SomethingSomething, Feb 23 '17 at 15:44

This is not generically possible. E.g. for SIGKILL, you user program has no control. The operating system will simply terminate it. Cf. SIGKILL signal handling or SIGKILL signal Handler

Let's currently ignore the `kill -9` kind of kill, that can't anyway be handled. I mean to all other termination types – SomethingSomething Feb 23 '17 at 15:02
Please update the question accordingly. SIGKILL is explicitly stated there. – languitar Feb 23 '17 at 15:36
