is there a way to catch SIGINT in a custom signal handler while os.sys

Hey everyone, is there a way to catch SIGINT in a custom signal handler while os.system is executing?'s: https://mail.python.org/pipermail/python-list/2002-April/127700.html Like I want a custom signal handler to catch the SIGINT in my python code, but the signal is going directly to the process running in os.system (on pressing Ctrl+C)

yes, it's possible, but not with os.system(). Check out python's subprocess module (the Popen part) in the preexec_fn you can call os.setpgrp() which does prevent forwarding signals to the sub process iirc. you can define your custom signal handler using the signal module, or catch KeyboardInterrupt with a try-except block
