# 设计一个Game类 要求定义一个类属性 top_score 记录游戏的历史最高分定义一个实例属性 player_name 记录当前游戏的玩家姓名 主程序步骤1 查看帮助信息2 查看历史最高分3 创建游戏对象，开始游戏

好的，这是一个简单的实现：

class Game:
    top_score = 0
    
    def __init__(self, player_name):
        self.player_name = player_name
        
    def start_game(self):
        print(f"Let's start the game, {self.player_name}!")
        
        # 游戏逻辑代码
        
        score = 100  # 假设当前玩家得到了100分
        
        if score > Game.top_score:
            Game.top_score = score
            print("Congratulations! You have set a new top score!")
        else:
            print(f"Your score is {score}. The top score is {Game.top_score}. Keep trying!")

然后在主程序中可以这样使用：

def main():
    print("Welcome to the game!")
    print("Type 'help' for help information.")
    
    while True:
        command = input("> ")
        
        if command == "help":
            print("This is a simple game. Just enjoy it!")
        
        elif command == "top score":
            print(f"The top score is {Game.top_score}.")
            
        elif command == "start":
            player_name = input("Please enter your name: ")
            game = Game(player_name)
            game.start_game()
            
        elif command == "exit":
            print("Goodbye!")
            break
        
        else:
            print("Invalid command. Please try again.")

这样，当用户输入"start"命令时，就会创建一个Game对象并开始游戏。每次游戏结束后，会更新历史最高分，并显示给玩家。
