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。
