设计一个会员卡计费管理系统，根据下面内容自行设计会员个人信息及会员卡信息，至少具有下面 所要求的基本内容，并通过菜单实现相应功能。 (1)新会员登记。(将会员个人信息及此会员的会员卡信息进行录入。) (2)会员信息修改。 (3)会员续费。(会员出示会员卡后，管理人员根据卡号查找到该会员的信息并显示。此时可以 行续费，续费后，提示成功，并显示更新后的信息。) (4)会员消费结算。(会员出示会员卡后，管理人员根据卡号查找到该会员的信息，结算本次费用。提示成功，并显示更新后的信息。)累计消费满1000元，及自动升级为VIP会员。之后每次消费给9折优惠。 (5)会员退卡。(收回会员卡，并将余额退还，删除该会员信息。) 会员卡挂失。(为该会员补办新卡，并将旧卡余额转至新卡。) (9) (7)统计功能:能够按累计消费总额进行排序。在排序的最后一行显示所有会员的缴费总额，以 消费总额。

好的，根据您提供的要求，我可以给您设计一个简单的会员卡计费管理系统。该系统基于 Python 编写，使用文件存储数据。以下是系统的基本功能：

1. 新会员登记：将会员个人信息及会员卡信息进行录入并保存到文件中。

2. 会员信息修改：根据会员卡号查找会员信息，并可修改会员个人信息及会员卡信息。

3. 会员续费：根据会员卡号查找会员信息并显示，进行续费操作后保存信息。

4. 会员消费结算：根据会员卡号查找会员信息并显示，进行结算操作后保存信息。如累计消费满 1000 元，自动升级为 VIP 并享受 9 折优惠。

5. 会员退卡：根据会员卡号查找会员信息并删除。

6. 会员卡挂失：根据会员卡号查找会员信息并进行挂失操作后保存信息，同时为会员补办新卡并将旧卡余额转至新卡。

7. 统计功能：按照累计消费总额排序，并在排序的最后一行显示所有会员的缴费总额及消费总额。
