• 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
