python - Non-polling/Non-blocking Timer?

Question

The best solution I've found so far is to just use the sleep() function. I'd like to run my own callback function when the event of a timer expiration happens. Is there any event-driven way to go about it?

from time import sleep

# Sleep for a minute
time.sleep(60)

Answer 1

There's a built-in simple solution, using the threading module:

import threading

timer = threading.Timer(60.0, callback)
timer.start()  # after 60 seconds, 'callback' will be called

## (in the meanwhile you can do other stuff...)

You can also pass args and kwargs to your callback. See here.
