python 如何将ppt和word转化为txt文档

89 阅读 0 评论 59 点赞

我是靠谱客的博主花痴蜜粉，这篇文章主要介绍python 如何将ppt和word转化为txt文档，现在分享给大家，希望可以做个参考。

　　最近做了关于计算文档中关键词的程序，使用Tf-idf方法去提取，其中需要使用python读取MS word文档和 MS powerpoint中的内容，现将部分讲解和代码贴出来，请指正。

　　首先，介绍一下win32com，这是个和window链接的模块，实话说，功能是很强大的，在网上看到很多功能，可以用来打开word，ppt，Excel，Access，模拟浏览器等行为，下载地址：http://starship.python.net/~skippy/win32/Downloads.html，现在，介绍其功能，是从其他网上的资料粘贴过来的。

1.word功能：http://my.oschina.net/duxuefeng/blog/64137（这个写的比较清楚）
