Better handling of KeyboardInterrupt in cmd.Cmd command line interpreter

Question

While using python\'s cmd.Cmd to create a custom CLI, how do I tell the handler to abort the current line and give me a new prompt?

Here is a minimal example:

Answer 1

I prefer the signal method, but with just pass. Don't really care about prompting the user with anything in my shell environment.

import signal

def handler(signum, frame):
    pass

signal.signal(signal.SIGINT, handler)
