python擷取檔案版本資訊、公司名和產品名的方法_python

本文執行個體講述了python擷取檔案版本資訊、公司名和產品名的方法,分享給大家供大家參考。具體如下：

該python代碼可得到檔案版本資訊、公司名和產品名。其他的資訊都在返回的字典中。具體代碼如下：

  def _getCompanyNameAndProductName(self, file_path):     """     Read all properties of the given file return them as a dictionary.     """     propNames = ('Comments', 'InternalName', 'ProductName',       'CompanyName', 'LegalCopyright', 'ProductVersion',       'FileDescription', 'LegalTrademarks', 'PrivateBuild',       'FileVersion', 'OriginalFilename', 'SpecialBuild')        props = {'FixedFileInfo': None, 'StringFileInfo': None, 'FileVersion': None}        try:       # backslash as parm returns dictionary of numeric info corresponding to VS_FIXEDFILEINFO struc       fixedInfo = win32api.GetFileVersionInfo(file_path, '\\')       props['FixedFileInfo'] = fixedInfo       props['FileVersion'] = "%d.%d.%d.%d" % (fixedInfo['FileVersionMS'] / 65536,           fixedInfo['FileVersionMS'] % 65536, fixedInfo['FileVersionLS'] / 65536,           fixedInfo['FileVersionLS'] % 65536)          # \VarFileInfo\Translation returns list of available (language, codepage)       # pairs that can be used to retreive string info. We are using only the first pair.       lang, codepage = win32api.GetFileVersionInfo(file_path, '\\VarFileInfo\\Translation')[0]          # any other must be of the form \StringfileInfo\%04X%04X\parm_name, middle       # two are language/codepage pair returned from above          strInfo = {}       for propName in propNames:         strInfoPath = u'\\StringFileInfo\\%04X%04X\\%s' % (lang, codepage, propName)         ## print str_info         strInfo[propName] = win32api.GetFileVersionInfo(file_path, strInfoPath)          props['StringFileInfo'] = strInfo     except:       pass     if not props["StringFileInfo"]:       return (None, None)     else:       return (props["StringFileInfo"]["CompanName"], props["StringFileInfo"]["ProductName"])
