Killing process help

Hello, I need to make a python file for close a process
The problem is the next:
I want the user doesn't see the CMD window..
Does it's possible ?

import os
os.system("taskkill /im injector* /f")
os.system("taskkill /im *injector /f")

Thanks in advance !

I don't really understand why you wouldn't want your CMD window not to be running but you could possibly run:

import os

pid = os.getpid()
os.kill(pid,2)
