利用DeepSeek辅助把幻灯片markdown文件转换成pdf
1.在DeepSeek对话框上传markdown文件，并提示
编写python程序，读入附件格式的md文件，用适当的库生成pdf格式幻灯片，只要一个代码，不做别的
它的输出:
以下Python程序可以读取您提供的Markdown格式课件，并使用适当的库生成PDF格式的幻灯片：

- 安装依赖库：
pipinstallmarkdown weasyprint- 运行程序：
python md_to_pdf_slides.py程序功能说明
- 自动分页：根据Markdown的一级标题（
#开头）自动分割幻灯片 - 保留格式：完整保留Markdown的表格、列表、引用等格式
- 美观样式：
- 标题使用亮黄色/橙色
- 正文为浅灰色
- 关键词和重点内容突出显示
- 互动提问框特殊样式
- 页码标注：每页幻灯片底部显示页码
- 响应式设计：适应不同纸张大小
生成的PDF将完美呈现您提供的课件内容，包括表格、互动提问、思考题等所有元素。

参考提示网页https://doc.courtbouillon.org/weasyprint/stable/first_steps.html#installation的说明
在 https://www.msys2.org/#installation 下载了 https://github.com/msys2/msys2-installer/releases/download/2025-12-13/msys2-x86_64-20251213.exe 安装并运行。
在msys2命令行中输入pacman -S mingw-w64-x86_64-pango，自动安装各种库。
回到windows cmd控制台，输入如下命令行。
C:\d>set WEASYPRINT_DLL_DIRECTORIES=C:\d\msys64\mingw64\bin C:\d>python md2pdf.py ✅ PDF幻灯片已成功生成：计算机常识科普课件.pdf 📊 共生成 13 页幻灯片注意：必须安装msys2，我的机器原来就安装过mingw64，但它不包括libgobject-2.0-0.dll文件，将WEASYPRINT_DLL_DIRECTORIES设成它的路径还是报同样的错。
