But you can't you're not connected when I tried just to print the s.recv(1024) I got this error:

[WinError 10057] A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied

Ah Windows, maybe try this instead:

python3 -m http.server 9003 --bind 127.0.0.1

And I believe it should be conn.recv to read from the accepted client socket, not s.recv to read from the listening socket.

Yes of course I set the VAR_HOST variable the problem is that you can't call the recv function to receive the data if you don't start a connection

That's it exactely it should be conn.recv to read from the client socket, not s.recv, thanks :)
