Run a function at forceful termination of the script in Python

Question

I have created a log and want it to be updated at forceful termination of the python script. This will help in keeping a track of all the forceful terminations. I tried , but atexit() runs only on normal termination.

Answer 1

Just catch the KeyboardInterrupt exception.

This simple program demonstrates how a function can be run when the Ctrl+C key combination is pressed to exit.

def main():
    while True:
        input('')

def onexit():
    print('on exit')

try:
    main()
except KeyboardInterrupt:
    onexit()
