在现代商业和教育环境中，PowerPoint演示文稿是信息传递的重要工具。通过Python自动化PPT创建和编辑过程，可以大幅提高工作效率，特别是在需要批量生成或更新演示文稿的场景下。本文将介绍如何使用python-pptx库实现PPT自动化，并提供实用的代码示例和应用场景。

使用python-pptx操作PPT文档

安装python-pptx

pip install python-pptx

基础概念

在Python中，可以使用python-pptx库实现PPT文件的自动化操作。需要注意的是，python-pptx只支持*.pptx文件格式的PPT文件（Office 2007及以上版本）。

一个PPT文件通常由多个幻灯片组成，每个幻灯片都有相应的布局。通过python-pptx库创建PPT文件的过程其实就是创建一个空的PPT文件，然后不断向其中添加具有某种布局的幻灯片的过程。

创建新的PPT文档
