Is there anyway I can make my script execute one of my functions when Ctrl+c is hit when the script is running?

Take a look at signal handlers. CTRL-C corresponds to SIGINT (signal #2 on posix systems).

Example:

#!/usr/bin/env python
import signal
import sys
def signal_handler(signal, frame):
    print 'You pressed Ctrl+C - or killed me with -2'
    sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
print 'Press Ctrl+C'
signal.pause()
