使用类创建游戏菜单

class MenuItem:
    def __init__(self, name, action):
        self.name = name
        self.action = action

    def select(self):
        self.action()

# 创建菜单选项的动作函数
def start_game():
    print("游戏开始！")

def load_game():
    print("加载游戏...")

def quit_game():
    print("退出游戏")

# 创建菜单选项对象
start_item = MenuItem("开始游戏", start_game)
load_item = MenuItem("加载游戏", load_game)
quit_item = MenuItem("退出游戏", quit_game)

# 将菜单选项添加到菜单列表中
menu = [start_item, load_item, quit_item]

# 显示菜单
for item in menu:
    print(item.name)

# 用户选择菜单选项
choice = input("请选择菜单选项：")

# 根据用户选择执行相应的动作
for item in menu:
    if item.name == choice:
        item.select()
        break
