How can I override the keyboard interrupt? (Python)

Question

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

Answer 1

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()

Use the KeyboardInterrupt exception and call your function in the except block.

Answer 3

Sure.

try:
  # Your normal block of code
except KeyboardInterrupt:
  # Your code which is executed when CTRL+C is pressed.
finally:
  # Your code which is always executed.
