1.借助shelve模块，完成将数据
"week": ["Sun", "Mon", "Tues", "Wed", "Thur", "Fri", "Sat"]
"person": {"name": "Zero", "age": 8, "height": 180}
序列化到date.shl文件中
并反序列化来测试文件中的数据：如访问数据 "Tues"及"Zero"
探索：
自定义一个有打印语句的简单函数，将函数序列化到文件中，在反序列化测试函数中的打印语句

3.模拟加密过程
1）账号密码由用户键盘输入
2）对得到的账号密码进行md5方式加密处理(采取加盐)
3）提前建立基本的碰撞测试库
4）对于用户输入的账号密码进行反馈
