最近无聊又写了一个信用卡业务的练习。基于python3。功能如下：
模拟实现一个ATM+购物商城的程序
1.额度15000
2.实现购物商城，买东西加入购物车，调用信用卡接口结账
3.可以提现，手续费5%
4.每月22号出账单，每月10号为还款日，过期未还，按欠款总额的万分之5每日计息
5.支持多账户登录
6.支持账户间转账
7.记录每月日常消费流水
8.提供还款接口
9.ATM记录操作日志
10.提供管理接口，包括添加账户，用户额度，冻结账户
目前除了还款提醒没有实现，因为没有想到有什么方式比较简单，其他功能都已基本实现。代码中使用的都是标准包，代码也比较基础，适合新手，老鸟勿打击。本次练习项目共是哪个模块：atm（信用卡业务）、shopping（商城）和home（主模块），见源码：
