Basic websocket server and client implemented in python using tornado....

tornadoWebsocketClient.py

import websocket
import thread
import time

def on_message(ws, message):
    print message

def on_error(ws, error):
    print error

def on_close(ws):
    print "### closed ###"

def on_open(ws):
    def run(*args):
        for i in range(20):
            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:8888/ws",
                                on_message = on_message,
                                on_error = on_error,
                                on_close = on_close)
    ws.on_open = on_open

    ws.run_forever()

tornadoWebsocketServer.py

import tornado.httpserver
import tornado.websocket
import tornado.ioloop
import tornado.web

class EchoWebSocket(tornado.websocket.WebSocketHandler):
    def open(self):
        print "WebSocket opened"

    def on_message(self, message):
        print "Received message from client "+message
        self.write_message(u"You said: " + message)

    def on_close(self):
        print "WebSocket closed"


application = tornado.web.Application([
    (r'/ws', EchoWebSocket),
])
 
 
if __name__ == "__main__":
    http_server = tornado.httpserver.HTTPServer(application)
    http_server.listen(8888)
    tornado.ioloop.IOLoop.instance().start()
