How to Close a program using python?

Question

Is there a way that python can close a windows application (example: Firefox) ?

I know how to start an app, but now I need to know how to close one.

Answer 1

# I have used os comands for a while # this program will try to close a firefox window every ten secounds  import os import time  # creating a forever loop while 1 :     os.system("TASKKILL /F /IM firefox.exe")     time.sleep(10) 

Answer 2

in windows you could use taskkill within subprocess.call:

subprocess.call(["taskkill","/F","/IM","firefox.exe"]) 

/F forces process termination. Omitting it only asks firefox to close, which can work if the app is responsive.

Cleaner/more portable solution with psutil (well, for Linux you have to drop the .exe part or use .startwith("firefox"):

import psutil,os for pid in (process.pid for process in psutil.process_iter() if process.name()=="firefox.exe"):     os.kill(pid) 

that will kill all processes named firefox.exe

By the way os.kill(pid) is "overkill" (no pun intended). process has a kill() method, so:

for process in (process for process in psutil.process_iter() if process.name()=="firefox.exe"):     process.kill()
