Using signal.alarm() for a timeout

The Python signal module let’s you setup Unix signals, including SIGALRM. This can be used to setup a timeout : import signal def handler(signum, frame): print ‘received’, signum # Setup the handler signal.signal(signal.SIGALRM, handler) # Trigger the alarm after 60 seconds signal.alarm(60) This prints ‘received 14’ after 60 seconds.
