Is this a proper way to delect disconnect inside a loop (socketio.AsyncNamespace)

[4n1qz5skwv]

class IndexSio(socketio.AsyncNamespace):
    async def on_connect(self, sid, *_, **__):
        ...

    async def on_disconnect(self, sid, *_, **__):
        ...

    async def on_start(self, sid):
        while True:
            try:
                ddd = await self.get_session(sid)
            except KeyError:
                # Is this a safe place to assume that client has disconnected ?
                break
            print(f'{ddd=}')

Hint: the comment (except block)

The disconnect event is invoked when a client disconnects. There is no need for you to repeatedly get the session just to see if that errors out. For example, you can use an Event object in your on_start event handler for each client, which you signal from the disconnect handler.

Thank you. It helped 👍

May be in future, we will have a built-in property, something like self.is_connected 🤞
