Python-07PDF转Word

2025-03-04-PDF转Word

DeepSeek等大模型从来都不是简单的写一个静态博客这么肤浅（太多博主都只讲这个内容了）借助全网大神的奇思妙想，拓展我狭隘的思维边界。

1-参考网址

• DeepSeek编写一个PDF转Word软件(参考当前)：https://blog.csdn.net/henanlion/article/details/145861672
• 个人尝试代码仓库：https://gitee.com/enzoism/pdf2word

2-学习要点

• 1）思维拓展-DeepSeek如何辅助编程
• 2）Python-编写PDF转Word：https://blog.csdn.net/2301_77717148/article/details/146015704
• 3）Python-使用tkinter：https://blog.csdn.net/2301_77717148/article/details/146015225
• 4）Python-使用threading和queue：https://blog.csdn.net/2301_77717148/article/details/146013352
• 5）Python-编写Requirements.txt：https://blog.csdn.net/2301_77717148/article/details/146012907

3-核心逻辑

• 1）使用pdf2docx库将PDF文件转换为Word文件
• 2）使用tkinter实现GUI界面
• 3）使用threading和queue实现多线程和消息队列通信
• 4）使用Requirements.txt管理依赖库
