Answer 1

来自this answer :

import os
import subprocess

def logoff():
    ppid = os.environ['PPID']
    subprocess.call(["kill", "-HUP", ppid])

您必须捕获 KeyboardInterrupt异常(exception):

def main():
    try:
        display_status()
    except KeyboardInterrupt:
        logoff()


def display_status():
    pass  # your code goes here

if __name__ == '__main__':
    main()
