Run atexit() when python process is killed

Question

I have a python process which runs in background, and I would like it to generate some output only when the script is terminated.

def handle_exit():
    print(\'         


        

Answer 1

To check your system and see which signal is being called:

import signal
import time


def handle_signal(sig_id, frame):
    sig = {x.value: x for x in signal.valid_signals()}.get(sig_id)
    print(f'{sig.name}, {sig_id=}, {frame=}')
    exit(-1)


for sig in signal.valid_signals():
    print(f'{sig.value}: signal.{sig.name},')
    signal.signal(sig, handle_signal)

time.sleep(30)
