How to run multiple exe programs at the same time using python?

Question

I want to run multiple exe programs at the same time using python. Can you help me?

import os
    os.system( '"C:\\Users\\FOLDER\\MLTPad1.exe"' )
    os.system('"C:\\Users\\FOLDER2\\MLTPad2.exe"')

Answer 1

import threading 

def exe1(): 

    os.system( '"C:\\Users\\FOLDER\\MLTPad1.exe"' )

def exe2(): 
    os.system('"C:\\Users\\FOLDER2\\MLTPad2.exe"')

if __name__ == "__main__": 
    # creating thread 
    t1 = threading.Thread(target=exe1, args=()) 
    t2 = threading.Thread(target=exe2, args=()) 

    # starting thread 1 
    t1.start() 
    # starting thread 2 
    t2.start() 

    # wait until thread 1 is completely executed 
    t1.join() 
    # wait until thread 2 is completely executed 
    t2.join() 

    # both threads completely executed 
    print("Done!") 

What happens here is that both your exes are put into separate functions, which then are run parallely using the concept of multithreading implemented via threading class of Python.

Hope it helps!

If you just want to spawn separate processes, then you can use something like

from subprocess import Popen
print(Popen(['notepad.exe']).pid)
print(Popen(['calc.exe']).pid)
