How to stop an infinite loop safely in Python?

Question

I\'ve got a script that runs on a infinite loop and adds things to a database and does things that I can\'t just stop halfway through so I can\'t just press ctrl+C and stop

Answer 1

the below logic will help you do this,

import signal
import sys
import time

run = True

def signal_handler(signal, frame):
    global run
    print "exiting"
    run = False

signal.signal(signal.SIGINT, signal_handler)
while run:
    print "hi"
    time.sleep(1)
    # do anything
    print "bye"

while running this, try pressing CTRL+C
