    def run(*args):
        for i in range(3):
            time.sleep(1)
            ws.send("Hello %d" % i)
        time.sleep(1)
        ws.close()
        print "thread terminating..."
    thread.start_new_thread(run, ())


if __name__ == "__main__":
    websocket.enableTrace(True)
    ws = websocket.WebSocketApp("ws://localhost:5000/chat",
                                on_message = on_message,
                                on_error = on_error,
                                on_close = on_close)
    ws.on_open = on_open

    ws.run_forever()
