Python で CMS システム用のカスタム メニュー関数を作成する方法

class Menu:
    def __init__(self):
        self.menu_items = {}
        
    def add_menu_item(self, name, path):
        self.menu_items[name] = path
        
    def remove_menu_item(self, name):
        if name in self.menu_items:
            del self.menu_items[name]
        
    def get_menu_items(self):
        return self.menu_items

def show_menu(menu):
    print("===== 自定义菜单 =====")
    menu_items = menu.get_menu_items()
    
    for index, (name, path) in enumerate(menu_items.items(), start=1):
        print(f"{index}. {name}")
        
    print("====================")
    
    choice = int(input("请选择一个菜单项: "))
    
    if 1 <= choice <= len(menu_items):
        selected_menu_item = list(menu_items.keys())[choice - 1]
        print(f"你选择了菜单项 '{selected_menu_item}'，页面路径为 '{menu_items[selected_menu_item]}'")
    else:
        print("无效的选择！")

def main():
    menu = Menu()
    
    menu.add_menu_item("首页", "/")
    menu.add_menu_item("文章列表", "/articles")
    menu.add_menu_item("用户管理", "/users")
    
    show_menu(menu)

if __name__ == "__main__":
    main()
