Comment

from threading import Thread, Event
from time import sleep

evt = Event()
result = None

def background_task(): 
    global evt, result
    print("start")
    result = "Started"
    sleep(5)
    print("stop")
    result = "Finished"
    evt.set()

Thread(target=background_task).start()

# Wait for variable to change
# (Optional timeout)
evt.wait(timeout=3)
print(result)
# Not so sophisticated, is it?
