Convert tornado websocket object to json to identify the client

class ChatWebSocket(tornado.websocket.WebSocketHandler):
    clients = []
    def open(self):
        ChatWebSocket.clients.append(self)

        self.write_message(self)      
    def on_message(self, message):
        print(self)
        self.write_message('{"a":"SDF"}') 

    def on_close(self):
        ChatWebSocket.clients.remove(self)

I want to convert the self object in a json and send it to the client so that I can identify the request on_message and deliver the message to appropriate client.

Actually you do something wrong. You don't need to convert self to json and send it to the client. Every instance of ChatWebSocket has information about its ws-connection. So method write_message send the message to appropriate client.

def write_message(self, message, binary=False):
    if isinstance(message, dict):
        message = tornado.escape.json_encode(message)
    self.ws_connection.write_message(message, binary=binary)
