How to continously get current block number

[ma7555]

Hello,
I have seen your comment here

I am trying to do the same using sockets, this is my adapted code but it does not seem to work

import asyncio
from web3_proxy_providers import AsyncSubscriptionWebsocketProvider
from connector import provider_quicknode_wss


async def callback(subs_id: str, json_result):
    print(json_result)


async def main(loop: asyncio.AbstractEventLoop):
    provider = AsyncSubscriptionWebsocketProvider(
        loop=loop,
        websocket_endpoint_uri="wss_url",
    )

    subscription_id = await provider.subscribe(
        ["logs", {"address": "newHeads", "topics": []}], callback
    )
    print(f"Subscribed with id {subscription_id}")

    # unsubscribe after 30 seconds
    await asyncio.sleep(30)
    await provider.unsubscribe(subscription_id)


if __name__ == "__main__":
    async_loop = asyncio.get_event_loop()
    async_loop.run_until_complete(main(loop=async_loop))
