deepseek 对话编写 【使用python编写一个物料编码申请的erp系统】

 1.效果如下

实现了增删改查，数据保存

2.操作方法

使用 csdn一直推荐的 trace cn，通过选择deepseek进行对话操作

 把终端配置成git bash

从这边配置

 

3.配置好后就直接提问题就好

 

 主要就是点击运行和应用

这个就是想改一下编码方式，直接说，按他提示应用就好

其他的也是这样

4.命令行方式运行

运行起来就是这种效果

5.让他直接搞成网页

 

就是这么地运行应用

像这种的有问题的也是直接添加到对话，他也是会修改，直接应用就好。

搞完就是开篇的效果

6.代码及文件结构

这个就是搞了两个小时的最后的文件结构
