I was doing some reading(1,2,3) because I wanted to learn how to stop a thread properly.

I came up with a trivial example:

import time
import threading


def counting_numbers(stopper):
    for num in range(1,20):
        if not stopper.is_set():
            print(num)
            stopper.wait(2)


stop = threading.Event()
write = threading.Thread(target=counting_numbers, args=(stop,))
write.start()
time.sleep(5)
stop.set()

Suppose if this was a GUI application and I had a cancel button, would the stop.set() go inside the cancel button handler allowing the user to hit cancel and stop the count?

  • Did you try it? did it work? – wwii Nov 16 '17 at 16:42

    It did work, BUT just because it worked doesn't mean it's the proper practice or even the correct way of doing things –  Nov 16 '17 at 17:04
