python获取文件版本信息、公司名和产品名的方法

本文实例讲述了python获取文件版本信息、公司名和产品名的方法,分享给大家供大家参考。具体如下：

该python代码可得到文件版本信息、公司名和产品名。其他的信息都在返回的字典中。具体代码如下：

      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"]) 

希望本文所述对大家的Python程序设计有所帮助。
