Button to stop while loop from another script

[deanhystad]

The global variable belongs in script B, not script A.

napper.py is a script that that contains a function I want to interrupt.

import time

wake_up = True

def take_a_nap():
    global wake_up
    wake_up = False
    print("I'm taking a nap.")
    while not wake_up:
        time.sleep(1)
        print("Zzzzzz")
    print("I'm awake")

test.py is a script that uses napper.

import threading
import time
import napper

t1 = threading.Thread(None, napper.take_a_nap)
t1.start()
time.sleep(5)
print("Time to wake up!")
napper.wake_up = True
t1.join()
print("Good morning")

Output:
I'm taking a nap.
Zzzzzz
Zzzzzz
Zzzzzz
Zzzzzz
Time to wake up!
Zzzzzz
I'm awake
Good morning
