我是靠谱客的博主花痴蜜粉，最近开发中收集的这篇文章主要介绍python 如何将ppt和word转化为txt文档，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

　　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）　

 1 import win32com
 2 from win32com.client import Dispatch, constants
 3
 4 w = win32com.client.Dispatch('Word.Application')
 5 # 或者使用下面的方法，使用启动独立的进程：
 6 # w = win32com.client.DispatchEx('Word.Application')
 7
 8 # 后台运行，不显示，不警告
 9 w.Visible = 0
10 w.DisplayAlerts = 0
11
12 # 打开新的文件
13 doc = w.Documents.Open( FileName = filenamein )
14 # worddoc = w.Documents.Add() # 创建新的文档
15
16 # 插入文字
17 myRange = doc.Range(0,0)
18 myRange.InsertBefore('Hello from Python!')
19
20 # 使用样式
21 wordSel = myRange.Select()
22 wordSel.Style = constants.wdStyleHeading1
23
24 # 正文文字替换
25 w.Selection.Find.ClearFormatting()
26 w.Selection.Find.Replacement.ClearFormatting()
27 w.Selection.Find.Execute(OldStr, False, False, False, False, False, True, 1, True, NewStr, 2)
28
29 # 页眉文字替换
30 w.ActiveDocument.Sections[0].Headers[0].Range.Find.ClearFormatting()
31 w.ActiveDocument.Sections[0].Headers[0].Range.Find.Replacement.ClearFormatting()
32 w.ActiveDocument.Sections[0].Headers[0].Range.Find.Execute(OldStr, False, False, False, False, False, True, 1, False, NewStr, 2)
33
34 # 表格操作
35 doc.Tables[0].Rows[0].Cells[0].Range.Text ='123123'
36 worddoc.Tables[0].Rows.Add() # 增加一行
37
38 # 转换为html
39 wc = win32com.client.constants
40 w.ActiveDocument.WebOptions.RelyOnCSS = 1
41 w.ActiveDocument.WebOptions.OptimizeForBrowser = 1
42 w.ActiveDocument.WebOptions.BrowserLevel = 0 # constants.wdBrowserLevelV4
43 w.ActiveDocument.WebOptions.OrganizeInFolder = 0
44 w.ActiveDocument.WebOptions.UseLongFileNames = 1
45 w.ActiveDocument.WebOptions.RelyOnVML = 0
46 w.ActiveDocument.WebOptions.AllowPNG = 1
47 w.ActiveDocument.SaveAs( FileName = filenameout, FileFormat = wc.wdFormatHTML )
48
49 # 打印
50 doc.PrintOut()
51
52 # 关闭
53 # doc.Close()
54 w.Documents.Close(wc.wdDoNotSaveChanges)
55 w.Quit()

2. Excel功能：同上的网址

3. Access功能：

1 import win32com.client
2 oAccess = win32com.client.Dispatch('Access.Application')
3 DbFile = r'C:UsershansDocumentsNewDb.mdb'
4 dbLangGeneral = ';LANGID=0x0409;CP=1252;COUNTRY=0'
5 # dbVersion40 64
6 dbVersion = 64
7 oAccess.DBEngine.CreateDatabase(DbFile, dbLangGeneral, dbVersion)
8 oAccess.Quit()
9 del oAccess

4. 模拟浏览器行为：http://www.cnblogs.com/chenzehe/archive/2010/09/01/1814397.html

5.播放mp3文件：http://www.sharejs.com/codes/python/5733

 1 from win32com.client import Dispatch
 2 mp = Dispatch("WMPlayer.OCX")
 3 # use an mp3 file you have ...
 4 #tune = mp.newMedia("C:/Program Files/Common Files/HP/Memories Disc/2.0/audio/Swing.mp3")
 5 # or copy one to the working folder ...
 6 #tune = mp.newMedia("Bier1.mp3")
 7 # you can also play wma files, this cool sound came with XP ...
 8 tune = mp.newMedia("C:/WINDOWS/system32/oobe/images/title.wma")
 9 mp.currentPlaylist.appendItem(tune)
10 mp.controls.play()
11 # to stop playing use
12 raw_input("Press Enter to stop playing")
13 mp.controls.stop()

　　真心感觉这个东西很强大呀！言归正传，该上将word和ppt转化为txt的代码了！如下：
