前言：
本文基于Python语言环境实现，以及vsCode工具开发实现，能够反对ppt转pptx 或 pptx转ppt pdf png 等格局。
正式开发：
1、装置reportlab模块
#装置reportlab模块pip3 install reportlab2、装置win32com模块
第一种：
pip3 install pywin32第二种：
python -m pip install --upgrade pip -i https://pypi.douban.com/simple3、创立pptToPptx.py

第一种：cmd运行
找到文件目录输出：python pptToPptx.py
第二种：VSCode软件，配置python环境，运行
5、抉择序号，输出文件夹门路即可。
6、到所输出文件夹门路下的pptx文件下查看所有转换胜利的文件
7、实现，有帮忙，记得点赞，感激！
