I followed the youtube video and used python to make a multiplayer online game of rock-paper-scissors. When I execute the script, the console displays "Couldn't get game", which is generated when the client script does not receive the game sent by the server. My server script and client script can't seem to exchange information.
This program is not finished yet. The client script refers to the network script to receive and send messages, and the server script refers to the game script to execute the game.
This is the server script
