You'd usually use another thread to tell the loop when to exit, or run the loop itself in another thread: import sys,time from threading import Event, Thread def f(event): while not event.isSet(): sys.stdout.write('\a') sys.stdout.flush() time.sleep(0.5) a = Event() Thread(target=f, args=(a,)).start() raw_input('hit return when done: ') a.set() see the docs for the threading module, to make sense of this. -- http://mail.python.org/mailman/listinfo/python-list
