模拟实现ATM+购物商城的程序

Posted 2021-01-12 source12

 1 1、函数从ATM_Program--core下的main文件运行，其中的ATM功能只能有三次登录机会。登陆成功失败与否均不允许再次登陆。
 2 2、文件Bin下的atm.py是信用卡操作主程序：例如账户间转账、存钱、提现功能
 3 3、文件夹Bin下的是manager.py是信用卡的管理端：例如冻结账户、改变信用卡额度、添加账户。
 4 4、manager.py的主程序在accounts.py里。
 5 5、logger.py日志记录模块。记录账户登陆和，购物的流水。
 6 6、transaction.py与settings.py与db_handler.py与transaction.py均暂时没有内容
 7 7、db文件是用户数据存储的地方，account_sample.py能生成初始账户数据。
 8 8、accounts文件夹下面存放各个账户，一个账户一个文件
 9 9、log文件夹下面存放日志：用户访问和交易日志存放在同一个文件夹。
10 10、shooping_mall是电子商城程序。
