Run two python files at the same time

Question

I have tried using

#!/bin/bash
python ScriptA.py &
python ScriptB.py &

to run both scripts at the same time but it always returns

Answer 1

You have to import os module and use the system function from it, then separate the two Python files you are running by &&.

import os
def song():
    user = input()
    if user == "Chance":
        os.system('python ScriptA.py && python ScriptB.py')
    else:
        print("Error")

song()

But I will advice you to just import the two files you want to run into the third file and just run the functions in there like normal functions.

e.g.

import ScriptA
import ScriptB

ScriptA.function()
ScriptB.function()

If there are no functions inside the scripts, the script runs immediately after they are imported.

Answer 2

You can just open both files on the python IDLE and run each o them. If you need both files to run simultaneously (the first way you have the delay of pressing F5 on each file) you can use PyCharm and download the multirun plugin.

Answer 3

You can try os.system :

import os

os.system("python ScriptA.py &")
os.system("python ScriptB.py &")

Answer 4

I think you are looking for multi-threading

you could merge your both script into another script, then lauch them using theads

--edit--

from threading import Thread

import cv2
import numpy as np
import os
from playsound import playsound

def play_sound(): 
    # import your script A
    a = (r"C:\Users\A\Desktop\sound.mp3")
    playsound(a)

def CV2_stuff():
    # import your script B
    os.environ['SDL_VIDEO_CENTERED'] = '1'
    cap = cv2.VideoCapture("video.mp4")
    ...


Thread(target = play_sound).start() 
Thread(target = CV2_stuff).start()

hope it helps

this could work too

import ScriptA
import ScriptB

ScriptA.function()
ScriptB.function()

but they wouldn't be exectuted in the same time
