Python script in AUTOKEY program

import concurrent.futures
import subprocess
import os


# Change the current working directory
os.chdir('/home/user/Documents/VideoDownloader') #change to your working directory not where autokey stores scripts (/home/user/.config/autokey/data/Start_Up_Scripts/
with concurrent.futures.ProcessPoolExecutor() as executor:
    proc1 = executor.submit(subprocess.run, ['./downloader.sh'])
    proc2 = executor.submit(subprocess.run, ['./onlinedownloader.sh'])

proc1.result()
proc2.result()

Example of a bash script in ( /home/user/Documents/VideoDownloader ) or where ever.
