For ctrl+C you can `try`-`except KeyboardInterrupt`. What do you mean by "press the X button on the tab in the program"? — nog642, Jul 12 '20 at 21:06

You can register a function to be executed at exit. See the atexit module.

For example, this will call print('goodbye.') when exiting:

atexit.register(print, 'goodbye.')

You can also register any other function which will do the cleanup you need.

How to install the library ? – Oussema Nehdi Jul 12 '20 at 21:22
@OussemaNehdi It's in the standard library. You don't need to install it; it comes with Python. – nog642 Jul 12 '20 at 21:34
it does the functions on multiprocess? – Oussema Nehdi Jul 12 '20 at 22:04
also does this catch other OS level interrupts ? – Oussema Nehdi Jul 12 '20 at 22:05
