需求：
# 编写小说阅读程序实现下属功能
# 一：程序运行开始时显示
# 0 账号注册
# 1 充值功能
# 2 阅读小说
# 二： 针对文件db.txt，内容格式为："用户名:密码:金额",完成下述功能
# 2.1、账号注册
# 2.2、充值功能
# 三：文件story_class.txt存放类别与小说文件路径，如下,读出来后可用eval反解出字典
# {"0":{"0":["倚天屠狗记.txt",3],"1":["沙雕英雄转.txt",10]},"1":{"0":["令人羞耻的爱.txt",6],"1":["二狗的妻子与大草原的故事.txt",5]},}
# 3.1、用户登录成功后显示如下内容，根据用户选择，显示对应品类的小说编号、小说名字、以及小说的价格
"""
0 玄幻武侠
1 都市爱情
2 高效养猪36技
"""
# 3.2、用户输入具体的小说编号，提示是否付费，用户输入y确定后，扣费并显示小说内容，如果余额不足则提示余额不足
# 四：为功能2.2、3.1、3.2编写认证功能装饰器，要求必须登录后才能执行操作
# 五：为功能2.2、3.2编写记录日志的装饰器，日志格式为："时间 用户名 操作(充值or消费) 金额"
# 附加：
# 可以拓展作者模块，作者可以上传自己的作品
