any_connection = False

while True:
    try:
        conn, addr = s.accept()
         


        

Answer 1

You need to register a hook for this, something like:

#!/usr/bin/env python
import signal
import sys
def signal_handler(signal, frame):
        # close the socket here
        sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
