After my python flask app crushed without exiting, I tried using ctrl-C to stop it, instead of exiting the app I got ^C and for any other signal I tried via my keyboard as well, only control characters, as can be seen below:



To stop the process I had to open the best Linux terminal and send a kill signal from there.

This wasn't the first time I encounter this, What is causing this?

Is there a way to kill the process from within?

There's nothing wrong with the computer or the keyboard — the problem is just that the Python program is written in such a way that ^C is trapped. The only solution is to suspend it with ^Z and manually kill it, as explained here:
