I have the following basic code, which connects to a websocket server and receives some data:

import websocket, json, time

def process_message(ws, msg):
    message = json.loads(msg)
    print(message)

def on_error(ws, error):
    print('Error', e)

def on_close(ws):
    print('Closing')

def on_open(ws):
    def run(*args):
        Subs = []
       
        tradeStr=  """{"method": "SUBSCRIBE", "params":%s, "id": 1}"""%(json.dumps(Subs))
        ws.send(tradeStr)

    thread.start_new_thread(run, ())

def Connect():
    websocket.enableTrace(False)
    ws = websocket.WebSocketApp("wss://myurl", on_message = process_message, on_error = on_error, on_close = on_close)
    ws.on_open = on_open
    ws.run_forever()

Connect()

Now, i would like to create more connections to different servers and receive data concurrently in the same script. I tried the following:

def run(url):

    def process_message(ws, msg):
        message = json.loads(msg)
        print(message)

    def on_error(ws, error):
        print('Error', e)

    def on_close(ws):
        print('Closing')

    def on_open(ws):
        def run(*args):
            Subs = []
           
            tradeStr=  """{"method": "SUBSCRIBE", "params":%s, "id": 1}"""%(json.dumps(Subs))
            ws.send(tradeStr)

        thread.start_new_thread(run, ())

    def Connect():
        websocket.enableTrace(False)
        ws = websocket.WebSocketApp(url, on_message = process_message, on_error = on_error, on_close = on_close)
        ws.on_open = on_open
        ws.run_forever()

    Connect()

threading.Thread(target=run, kwargs={'url': 'url1'}).start()
threading.Thread(target=run, kwargs={'url': 'url2'}).start()
threading.Thread(target=run, kwargs={'url': 'url3'}).start()

Now, this code works, i'm connecting to different URLS and i'm streaming data from all of them, but it seemed to me an "hacky" solution, also i don't know if what i'm doing could be bad practice or not. Each connection will send around 600/700 small json dictionaries, and i need to update every record to the db. So my question is: is this implementation ok? Since it works with threads, can it create problems in the long run? Should i do another library such as Tornado? Any kind of advice is appreciated.
