How could a function look like, that can add an other function to a list of functions that run parallel in python?

Question

def update():
   while True:
       loadData()

def main():
   doStuff()
   addToParallelFunctions(update)
   doOtherStuff()

if __name__ == '__main__':
   addToParallelFunctions(main)

How could that addToParallelFunctions function look like, so that update runs parallel to main and that I can add other functions to run also parallel to the main ?

I've tried that, but it paused the main function and ran the other function until she was finished.

from multiprocessing import Process

def addProcess(*funcs):
    for func in funcs:
       Process(target=func).start()

I enhanced your example: It works for me. Main script and function continue both.

import time
from multiprocessing import Process

def addProcess(*funcs):
    for func in funcs:
       Process(target=func).start()

def update():
   for i in range(20):
       print(i)
       time.sleep(2)

def main():
   print("start")
   addProcess(update)
   print("Main function continues")

if __name__ == '__main__':
   addProcess(main)
   print("main script continues")

Next time, please post an example that is reproducible.
