原理是利用win32com接口直接调用office API，好处是简单、兼容性好，只要office能处理的，python都可以处理，处理出来的结果和office word里面“另存为”一致。

from win32com import client as wc 
word = wc.Dispatch('Word.Application') 
doc = word.Documents.Open('/FilePath/test.docx') 
doc.SaveAs('/DestPath/test.pdf', 17) #17对应于下表中的pdf文件
doc.Close() 
word.Quit()

• 1
• 2
• 3
• 4
• 5
• 6

下面是office 2007支持的全部文件格式对应表：

wdFormatDocument = 0
wdFormatDocument97 = 0
wdFormatDocumentDefault = 16
wdFormatDOSText = 4
wdFormatDOSTextLineBreaks = 5
wdFormatEncodedText = 7
wdFormatFilteredHTML = 10
wdFormatFlatXML = 19
wdFormatFlatXMLMacroEnabled = 20
wdFormatFlatXMLTemplate = 21
wdFormatFlatXMLTemplateMacroEnabled = 22
wdFormatHTML = 8
wdFormatPDF = 17
wdFormatRTF = 6
wdFormatTemplate = 1
wdFormatTemplate97 = 1
wdFormatText = 2
wdFormatTextLineBreaks = 3
wdFormatUnicodeText = 7
wdFormatWebArchive = 9
wdFormatXML = 11
wdFormatXMLDocument = 12
wdFormatXMLDocumentMacroEnabled = 13
wdFormatXMLTemplate = 14
wdFormatXMLTemplateMacroEnabled = 15
wdFormatXPS = 18

照着字面意思应该能对应到相应的文件格式。
