Unable to prevent program to print a Error

I took a piece of code from here: https://stackoverflow.com/a/10457565/13882705 which is

# 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)

It will terminate a process if it is running using OS module But if the program did not find the app we mentioned then it prints ERROR: The process "firefox.exe" not found.

Is there a way to make the program just print application not found once and wait until the program is rerunned?

It is fine even if it just prints "Application Not found"

Use subprocess.run instead of os.system so you have more control:

import subprocess
import time

while True:
    proc = subprocess.run(["TASKKILL", "/F", "/IM", "firefox.exe"], stderr=subprocess.PIPE)
    if proc.returncode != 0:
        print("Application not found.")
        break # since application isn't here we just exit
    time.sleep(10)
