Here's a good function header given the following:
I wrote the below code

    import sys
    from datetime import datetime
    import time
    def simpletest(event):
        six.print_(str(datetime.now()), event.route)
    ee = QueueEventEngine()
    timer = Timer(ee)
    ee.register(Event.TIMER, simpletest)
    ee.start()
    timer.start()
    time.sleep(2)
    timer.stop()
    time.sleep(2)
    timer.resume()
    try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        ee.stop()
        timer.stop()
        sys.exit(0)

What's a good function header?
