Python Forum - Is it Possible to pause a script?

Greetings!
I was wondering if it is possible to pause a Python script when it is running.
Ctrl+C aborts a script,
Is there anything I can do to pause it?

Thank you.

Yes, there is a way. In Unix/Linux there is a rich number of signals you can send to a process. I am not sure what is implemented of it in Windows.
I understand you run your program from the terminal/dosbox, for you say you do a <Ctrl>C. This sends the signal SIGINT (Interrupt) to the process. You can catch those signals. Read all about it in "signal — Set handlers for asynchronous events".
Example:

#! /usr/bin/env python3
import signal
import time

def handler(signum, frame):
    input("Progam paused. Hit enter to resume")
    return

signal.signal(signal.SIGINT, handler)

for i in range(10):
    print(i)
    time.sleep(1)

Output:$ ./signalexample.py

Outstanding!
ibreeden, thank you very much!

Pause a process: CTRL + Z
Continue the process: fg

No words! You are Da Man Wink

and I'm probably confused but CTRL+Z does not work...
What does it mean "Continue the process: fg" ?

Thank you

It works if you start the program from the linux terminal and then type ^Z in the terminal.

If you want to do the same outside the terminal, you could perhaps send SIGTSTP to the process to pause it and then SIGCONT to resume it.

I see.
Thank you!
You guys are awesome!
