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。
