im working on a project for my networking class which is a 2 clients plaing 4 in a row
I have almost everything figured out but i have one major issue, i need to get data from the server and in the same time do the mainloop beacuse i need the butons to appear, the mainloop line is blocking so when the code get to there he doesnt continue to the line that recv data from the server, how can i do the main loop and the recv data from the server at the same time?
any help would be great thanks. the server is:

server_socket.bind((SERVER_IP, SERVER_PORT))
server_socket.listen()
print("Listening for clients...")
