###程序简介：
>背景
#####作业：
* 购物车
* 三级菜单
***
>购物车构想
包含 0:注册 1:登陆 2:查询 3:充值 4:修改密码 5:解除锁定 6:退出等功能
采用json数据格式完成数据持久化
0:注册 采用json数据新增
1:登陆 采用三次验证规则，先判断有没有这个用户，然后判断是否是锁定状态，然后验证密码，错误超过三次锁定用户并退出系统
2:查询 将用户上次购买，历史购买，上次登陆信息以及余额显示出来
3:充值 将充值的金额与json中数据相加出新值
4:修改密码 判断old密码是否正确，错误退出。正确判断输入2次密码是否一致，一致写入文件
5:解除锁定 判断用户以及密码，来修改json中lock值
6:退出 exit
***
***
>三级菜单构想
1.定义一个字典，定义地区，省，市
2.嵌套2个 while True循环，一个为地区外循环，另一个为省市内循环
3.判断用户输入指令是否正确，不正确报错重新输入
4.判断用户输入是正确指令还是“b”or“q”，b:返回上一级 q:退出程序
