正如其他人提到的，您的代码确实需要很多更改。但在这里，我向你们提供了一些开始：

import random
import sys

class User:
    # ask user for name
    def __init__(self, name):
        self.name = User_name

class Results:
    # record user input
    def __init__(self):
        user_input = input("Pick rock, paper, or scissors?")

        self.selection = user_input

    def output(self):
        #return cpu output and run through the game

        cpu_output = random.choice(("rock", "paper", "scissors"))

        if self.selection == cpu_output:
            print(f" {User_name} it looks like we're tied")
        elif self.selection == "rock":
            if cpu_output == "paper":
                print(f"Paper beats rock. {User_name} it looks like I won this round")
            else:
                print(f"Great job {User_name}. Rock beats scissors it looks like you won this round")
        elif self.selection == "paper":
            if cpu_output == "scissors":
                print(f"Scissors beats paper. {User_name} it looks like I won this round")
            else:
                print(f"Great job {User_name}. Paper beats rock it looks like you won this round")
        elif self.selection == "scissors":
            if cpu_output == "rock":
                print(f"Rock beats scissors. {User_name} it looks like I won this round")
            else:
                print(f"Great job {User_name}. Scissors beats paper it looks like you won this round")

    def restart(self):
        #allow user to restart the game

        game_reset = input("Would you like to play again?")
        if game_reset == "Yes" or "yes":
            print(f"Starting up a new game {User_name}")
            self.output()
        else:
            print(f"Exiting the game. Thanks for playing {User_name}")
            sys.exit()

User_name = input("What is your name? ")
while True:
    result = Results()
    result.output()
    result.restart()

你没有 define 使用它们的函数，您可以 call 他们。
除此之外，还有一些问题。比如，游戏永远不会停止。在哪里进行调试？ if game_reset == "Yes" or "yes": 您确定这是检查连接的正确方法吗？或者你认为你遗漏了什么。是这样吗？检查并尝试找出答案。
所以是一个质疑的社会，明确的质疑。不是像这样的问题——“我的代码不起作用，修复它！”但不管怎样，你这里有些东西。
