装饰器练习（任意页面如果未登录都需要登录）

# 获取文件内容
def open_text(login_text):
    with open(login_text, "r", encoding="UTF-8") as file:
        file = eval(file.read())
        return file


login_flag = False


# 登录装饰器
def login_judge(file_text):
    def login_dl(f):
        def inner():
            global login_flag
            if not login_flag:
                name_password = open_text(file_text)
                name = input("请输入账号：")
                password = input("请输入密码：")
                if name == name_password["name"] and password == name_password["password"]:
                    print("登录成功！")
                    login_flag = True
                    f()
                else:
                    print("账号密码错误")
            else:
                f()
        return inner
    return login_dl


# 装饰器判断是否登录，页面内容展示
@login_judge("name_pw")
def book():
    print("book....")


@login_judge("wx")
def finance():
    print("finance....")


@login_judge("wx")
def home():
    print("home....")


# 选择打开那个页面
list_index = ["book", "finance", "home"]
while True:
    for index, i in enumerate(list_index):
        print(f"{index + 1}: {i}")
    input_number = input("请选择页面编号：")

    if input_number == "1":
        book()
    elif input_number == "2":
        finance()
    elif input_number == "3":
        home()
