import - How to stop another already running script in python?

Question

There is a way to start another script in python by doing this:

import os

os.system("python [name of script].py")

So how can i stop another already running script? I would like to stop the script by using the name.

Answer 1

It is more usual to import the other script and then invoke its functions and methods.

If that does not work for you, e.g. the other script is not written in such a way that is conducive to being imported, then you can use the subprocess module to start another process.

import subprocess

p = subprocess.Popen(['python', 'script.py', 'arg1', 'arg2'])
# continue with your code then terminate the child
p.terminate()

There are many possible ways to control and interact with the child process, e.g. you can can capture its stdout and sterr, and send it input. See the Popen() documentation.
