Making multiplayer games takes the surprisingly simple functionality utilized with socket programming and makes use of powerful abstractions in order to communicate game states/events. This tutorial covers a basic netcode case for a Tic-Tac-Toe Pygame game through the use of the built-in Python socket library.
