Make a Python Script that can run two python scripts concurrently

Question

I have two python programs that I want to run. I want to make a python script which execute the two scripts concurrently. How can I do that?

Answer 1

import os

import threading

def start():
    os.system('python filename.py')


t1 = threading.Thread(target=start)

t2 = threading.Thread(target=start)

t1.start()

t2.start()

Answer 2

You can also use a ThreadPoolExecutor from the concurrent.futures library and be more flexible on how many workers should be spawned to execute your target script. Something like this should just fine:

from concurrent.futures import ThreadPoolExecutor as Pool
import os

n_workers = 2

def target_task():
    os.system("python /path/to/target/script.py")

def main(n_workers):
    executor = Pool(n_workers)
    future = executor.submit(target_task)

if __name__ == "__main__":
    main(n_workers=n_workers)

This way you won't have to start your threads manually.
