I have a Pool of tasks in my code, I want an event to happen once all the tasks in the pool are done. I know about join method but it is stopping my main process of tkinter app, I used a list of Processes and I checked that list using thread whether all the processes are done

Right now I am trying to do like this : 

my_pool = [mp.Process(task).start() for task in tasks]
# checking if any process alive using a after method of tkinter
if not any(p.is_alive() for p in my_pool):
    # doing some event

I wonder if there is a way to do the same using mp.Pool instead of join(), because it is pausing the main UI of my app until all the process is done in that pool.

    My answer to the question [Freezing/Hanging tkinter Gui in waiting for the thread to complete](https://stackoverflow.com/questions/53696888/freezing-hanging-tkinter-gui-in-waiting-for-the-thread-to-complete) can probably be adapted to work with a multiprocessing `Pool` instead of multithreading. Be sure to use a `multiprocessing.Queue`. – martineau Apr 18 '20 at 14:41
