使用技巧

import win32com
from win32com.client import Dispatch, constants

w = win32com.client.Dispatch('Word.Application')
# 或者使用下面的方法，使用啟動獨立的進程：
# w = win32com.client.DispatchEx('Word.Application')

# 后臺運行，不顯示，不警告
w.Visible = 0
w.DisplayAlerts = 0

# 打開新的文件
doc = w.Documents.Open( FileName = filenamein )
# worddoc = w.Documents.Add() # 創(chuàng)建新的文檔

# 插入文字
myRange = doc.Range(0,0)
myRange.InsertBefore('Hello from Python!')

# 使用樣式
wordSel = myRange.Select()
wordSel.Style = constants.wdStyleHeading1

# 正文文字替換
w.Selection.Find.ClearFormatting()
w.Selection.Find.Replacement.ClearFormatting()
w.Selection.Find.Execute(OldStr, False, False, False, False, False, True, 1, True, NewStr, 2)

# 頁眉文字替換
w.ActiveDocument.Sections[0].Headers[0].Range.Find.ClearFormatting()
w.ActiveDocument.Sections[0].Headers[0].Range.Find.Replacement.ClearFormatting()
w.ActiveDocument.Sections[0].Headers[0].Range.Find.Execute(OldStr, False, False, False, False, False, True, 1, False, NewStr, 2)

# 表格操作
doc.Tables[0].Rows[0].Cells[0].Range.Text ='123123'
worddoc.Tables[0].Rows.Add() # 增加一行

# 轉(zhuǎn)換為html
wc = win32com.client.constants
w.ActiveDocument.WebOptions.RelyOnCSS = 1
w.ActiveDocument.WebOptions.OptimizeForBrowser = 1
w.ActiveDocument.WebOptions.BrowserLevel = 0 # constants.wdBrowserLevelV4
w.ActiveDocument.WebOptions.OrganizeInFolder = 0
w.ActiveDocument.WebOptions.UseLongFileNames = 1
w.ActiveDocument.WebOptions.RelyOnVML = 0
w.ActiveDocument.WebOptions.AllowPNG = 1
w.ActiveDocument.SaveAs( FileName = filenameout, FileFormat = wc.wdFormatHTML )

# 打印
doc.PrintOut()

# 關(guān)閉
# doc.Close()
w.Documents.Close(wc.wdDoNotSaveChanges)
w.Quit()

（3）處理excel

［1］使用PyExcelerator讀寫EXCEL文件(Platform: Win,Unix-like)
優(yōu)點：簡單易用      缺點：不可改變已存在的EXCEL文件。
PyExcelerator是一個開源的MS Excel文件處理python包。它主要是用來寫 Excel 文件.URL: http:///projects/pyexcelerator/
我沒有找到關(guān)于PyExcelerator的文檔。只是看到了limodou的一篇介紹。
http://blog.donews.com/limodou/archive/2005/07/09/460033.aspx
這個包使用起來還是比較簡單的：）。帶了很多小例子，可以參照。
例mini.py.

"導(dǎo)入模塊
from pyExcelerator import *
"生成一個工作薄
w = Workbook()
"加入一個Sheet
ws = w.add_sheet('Hey, Dude')
"保存
w.save('mini.xls')
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
[2]使用COM接口，直接操作EXCEL(只能在Win上)
優(yōu)點：可以滿足絕大數(shù)要求。缺點：有些麻煩。:-)
這方面的例子很多，GOOGLE 看吧:-). 文檔也可以參看OFFICE自帶的VBA EXCEL 幫助文件(VBAXL.CHM)。這里面講述了EXCEL VBA的編程概念，
不錯的教程！另外，《Python Programming on Win32》書中也有很詳細的介紹。這本書中給出了一個類來操作EXCEL 文件，可以很容易的加以擴展。
