Capture Control-C in Python

Question

I want to know if it's possible to catch a Control-C in python in the following manner:

 if input != contr-c:
    #DO THINGS
 else:
    #quit

I've read up on stuff with try and except KeyboardInterrupt but they're not working for me.

Answer 1

Consider reading this page about handling exceptions.. It should help.

As @abarnert has said, do sys.exit() after except KeyboardInterrupt:.

Something like

try:
    # DO THINGS
except KeyboardInterrupt:
    # quit
    sys.exit()

You can also use the built in exit() function, but as @eryksun pointed out, sys.exit is more reliable.

Answer 2

From your comments, it sounds like your only problem with except KeyboardInterrupt: is that you don't know how to make it exit when you get that interrupt.

If so, that's simple:

import sys

try:
    user_input = input()
except KeyboardInterrupt:
    sys.exit(0)
