Closing a running program from a process

问题

How can I close a program from a child process? For exanple:

import easygui
import multiprocessing

def func():
    reply=easygui.buttonbox("start?",image="F:\project\phonber.png",choices=['yes','no'])
    if reply=="yes":
        exit_option()


if __name__=='__main__':
    p=multiprocessing.Process(target=func,args=())
    t=p.start()
    while True:
        None

Is there a way to execute the exit_option() ?

Your forgot to actually call the function:

import easygui
import multiprocessing

def func():
    reply=easygui.buttonbox("start?",image="F:\project\phonber.png",choices=['yes','no'])
    if reply=="yes":
        exit_option()

func()


if __name__=='__main__':
    p=multiprocessing.Process(target=func,args=())
    t=p.start()
    while True:
        None

Then, to actually kill a running process there are, of course, many options. The most obvious ones being psutil its kill or terminate method, or os its kill method. Both as shown here.
