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

try:
s.bind((server, port))
except socket.error as e:
str(e)
s.listen()
print("Waiting for connection, Server Started")

CodePudding user response：
In the question you put three scripts network.py client.py server.py.
server.py called "Game" class from "game.py" and you did not put this script, firstly add this file to your project and run server.py, then run client1 and client2 (client2 it's a copy from client1), your code running well in my device after add "game.py" and "client2.py"
You can use the code in the following link, it's from the same source
https://github.com/BigYeser/multiplayer
I also advise you to change the ip address to 127.0.0.1
in server.py
server = "127.0.0.1"
port = 5555
in network.py
self.server = "127.0.0.1"
self.port = 5555
