How to override CTRL+Y in a python script?

Question

I want to implement Ctrl+Y as a hotkey in my python script, however, Ctrl+Y will cause a signal to be sent to my script, causing it to stop.

How can I override the Ctrl+Y key combination within the python script?

I have tried:

import signal
signal.signal(signal.SIGSTOP, signal.SIG_IGN)

but this will cause RunTimeError (22, 'invalid argument').

Whether or not CTRL+Y sends a signal to your script is terminal-dependent (and configurable from the terminal). – Amorist

The problem with your code is that you are trying to interrupt SIGSTOP which is uninterruptible. You want to interrupt SIGTSTP like so:

import signal
signal.signal(signal.SIGTSTP, signal.SIG_IGN)

That prevents ^Y from stopping the program, but the key still doesn't get transmitted, it's just ignored now. – Miyamoto
