How to unconditionally re-run a python program based on button click?

Question

At the end of my program execution, I want a popup message to appear that has a button which can re-run a program. Obviously, I will have setup a function that the button calls

This is potentially an over-simple approach, but say your existing program looks something like:

def my_app():
    # Code goes here

if __name__ == "__main__":
    my_app()

Instead wrap it like this:

def my_app():
    print("App is running!")
    # Your app code goes here
    print("App is exiting!")
    # On exit popup a prompt where selecting 'restart' sets restart_on_exit to True
    # Replace input() with a popup as required
    if input("Type y  to restart the app! ").lower() == "y":
        return True

if __name__ == "__main__":
    restart_on_exit = True
    while restart_on_exit:
        restart_on_exit = my_app()

That way the code will loop, running my_app over and over again, if the popup sets restart_on_exit to True before the loop repeats.
