https://github.com/x4nth055/pythoncode-tutorials/blob/master/python-standard-library/chat-application/server.py When I put all the code in server.py into VSCode, it suddenly shows an error `Code is unreachable Pylance` and it seems because `while True:` before : ```py # close client sockets for cs in client_sockets: cs.close() # close server socket s.close() ``` Can you update the code again, I need it :)
