Solve the following python programming problem given the following code:
def make_virtual_socket(host, port, path = '/ws') : 
    from websocket import WebSocketApp 
    result_handlers = { 
        
} 
    class Socket (object) : 
        def __init__(self) : 
            self._event_queues = defaultdict (Queue) 
def get_event_queue(self, event_type) : 
            return self._event_queues [event_type] 
def wait_for_event(self, event_type) : 
            return self.get_event_queue (event_type).get () 
def rpc(self, _method, **data) : 
            id = str (uuid.uuid4 ()) 
            event = Event () 
            result_handlers [id] = event.send 
            ws_app.send (json.dumps ({ 
                'method' : _method, 
                'data' : data, 
                'correlation_id' : id, 
})) 
            rv = event.wait () 
            if rv ['success'] : 
                return rv ['data'] 
raise deserialize (rv ['error']) 
sock = Socket () 
    def on_message(ws, message) : 
        msg = json.loads (message) 
        if (msg ['type'] == 'event') : 
            sock.get_event_queue (msg ['event']).put ((msg ['event'], msg ['data'])) 
else : 
            if (msg ['type'] == 'result') : 
                result_id = msg ['correlation_id'] 
                handler = result_handlers.pop (result_id, None) 
                if (handler is not None) : 
                    handler (msg) 
ready_event = Event () 
    def on_open(ws) : 
        ready_event.send (None) 
def on_error(ws, err) : 
        ready_event.send (err) 
ws_app = WebSocketApp (('ws://%s:%d%s' % (sock, port, path)), on_message = on_message, on_open = on_open, on_error = on_error) 
    def connect_socket() : 
        err = ready_event.wait () 
        if (err is not None) : 
            raise err 
return sock 
return (ws_app, connect_socket) 

    
    

    Fix the buggy line: ws_app = WebSocketApp (('ws://%s:%d%s' % (sock, port, path)), on_message = on_message, on_open = on_open, on_error = on_error)

#Here is Python code to fix the buggy line: ws_app = WebSocketApp (('ws://%s:%d%s' % (sock, port, path)), on_message = on_message, on_open = on_open, on_error = on_error)
.

ws_app = WebSocketApp (('ws://%s:%d%s' % (host, port, path)), on_message = on_message, on_open = on_open, on_error = on_error)
