How do I capture SIGINT in Python?

Question

I\'m working on a python script that starts several processes and database connections. Every now and then I want to kill the script with a Ctrl+C sign

Answer 1

Register your handler with signal.signal like this:

#!/usr/bin/env python
import signal
import sys

def signal_handler(sig, frame):
    print('You pressed Ctrl+C!')
    sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
print('Press Ctrl+C')
signal.pause()

Code adapted from here.

More documentation on signal can be found here.
