How to make a longlive connection client ?

[lowkey2016]

Just like this:

if __name__ == "__main__":
    websocket.enableTrace(True)
    ws = websocket.WebSocketApp("ws://echo.websocket.org/",
                              on_message = on_message,
                              on_error = on_error,
                              on_close = on_close)
    ws.on_open = on_open
    ws.run_forever()

#!/usr/bin/env python

import asyncio
import websockets

async def noop(uri):
    async with websockets.connect(uri) as websocket:
        async for message in websocket:
            pass

asyncio.get_event_loop().run_until_complete(
    noop('ws://echo.websocket.org/'))

PS - You're showing an example with callbacks. websockets operates at a higher level. You must forget about callbacks and learn coroutines (or choose a less advanced library).
