How to set a timer & clear a timer?

Question

I want to create a timer. When it times out, some actions will be taken. But, I can interrupt this timer and reset it. The pseudo code looks like below:

def timeo

The threading.Timer() class is likely what you're looking for:

from __future__ import print_function
from time import sleep
from random import random
from threading import Timer

def timeout():
    print("Alarm!")

t = Timer(10.0, timeout)
t.start()              # After 10 seconds, "Alarm!" will be printed

sleep(5.0)
if random() < 0.5:     # But half of the time
     t.cancel()        # We might just cancel the timer
     print('Canceling')
