How to cancel a loop with an Input?-CodePudding

I'm making a python console game, and one of the commands has a loop that keeps going for about 30 seconds. This can take longer depending on your level. When you're a higher level, the loop runs for many minutes. I've gotten many complaints and people asking me to add a cancel feature. I can't figure out how to cancel a loop early. How can I make the loop cancel early using an Input or something else?

Accept a character.
If the character is Q (for quit), then write break.

Syntax:

loop()
{
   char c
   input(c)
   if(c=='Q' or c=='q')
   {
       break
   }
   //other things in loop goes here.
}

If you want your loop to run in the background, maybe you need asyncio or threading.

Or you just want to cancel the loop, maybe you need signal to handle Ctrl-C or something else.

import signal

cancel_loop = False
def handler(signum, frame):
    print('sigint received')
    cancel_loop = True

signal.signal(signal.SIGINT, handler)

while not cancel_loop:
    # your code ...
