How to properly terminate threads on KeyboardInterrupt?

Question

Python

I want to simply exit the program using KeyboardInterrupt
, but I don’t understand where to handle this exception.

from threading import Thread
from time import sleep

def worker(i):
    while True:
        print("worker {}".format(i))
        sleep(i)

threads = [Thread(target=worker, args=(i,)) for i in range(1, 4)]
for t in threads:
    t.start()

for t in threads:
    t.join()

If KeyboardInterrupt processing is not needed by itself, but you want the process to be terminated by Ctrl + C, declare all threads as daemons.
