do something when terminate a python program

Question

I want make a python script do something such as publishing a message before terminating it. I have tried signal and it works when I input Ctrl+c in cmd window. However, it seems inoperative when I just directly close cmd window or kill the process from Windows task manager. So how can I reach my goal in the condition of above situation? Thanks for all suggestions!

I also have tried `atexit`, but it doesn't meet my need. – Da Vinci Mar 10 '17 at 01:25 — Da Vinci, Mar 10 '17 at 01:25

Take a look at the atexit module:

http://docs.python.org/library/atexit.html

Example:

import atexit

def exit_handler():
    print('My program just quit')

atexit.register(exit_handler)

Thanks for your help. I have a try according to your method, however, it's a pity that it doesn't work when I simply close the cmd window or click 'stop' in Pycharm where the python script is running. It works when I input `Ctrl+C` in cmd just like using `signal` method. – Da Vinci Mar 10 '17 at 01:23
