To stop code execution in Python you first need to import the sys object. After this you can then call the exit() method to stop the program from running. It is the most reliable, cross-platform way of stopping code execution.
Use exit() or quit() in the REPL. Use sys. exit() in scripts, or raise SystemExit() if you prefer.

Python quit() function
