6.16自我总结

功能介绍

程序功能介绍:
    商品信息再读取修改买卖均已xlsx格式
    且生成购物记录也按/用户名/购买时间.xlsx格式生成
    账号密码输入错误三次按照时间进行冻结
    用户信息已json格式保存
 程序写的过程
先生成功能模块和运行模块
再写功能模块中用到的固定的文件目录全放在setting.py文件中
与商品交互全放在shop.py中
与用户交互全放在user.py中
一些返回界面延迟动画全放在辅助模块中

1.程序设计目录

思路

• 生成xlsx文档就要导入pands模块
• 用户信息用josn保存导入json模块
• 把路径什么通用不变的丢入setting中
• 把所有文件存取丢入接口层中api中
• 其他增减根据功能来
• 一些通用的方法可以全部放入common中

2.run.py

from core.src import run
if __name__ == \'__main__\':
    run()

3.src.py

from conf.setting import *
from lib.common import *
from api.user import *
from api.shop import *
import re

import numpy as np
