对于windows文件，可以获得是否archive，文件的版本信息等；

代码：

import os

def TestFileAttributes():

# This function is platform indepedent.

statinfo = os.stat("c:\\python26\\python.exe")

print statinfo.st_size

print statinfo.st_atime

print statinfo.st_mtime

print statinfo.st_ctime

#statinfo also include other linux specific information.

#print statinfo

TestFileAttributes()

#27136

#1299820024.28

#1228458748.0

#1228458748.0

import stat

def TestForChangeToWrite(path):

# This is platform indepedent.

if not os.access(path,os.W_OK):

os.chmod(path,stat.S_IWRITE)

TestForChangeToWrite("c:\\python26\\python.exe")

#print info

print HIWORD (ms), LOWORD (ms), HIWORD (ls), LOWORD (ls)

get_version_number("C:\\Program Files\\7-Zip\\7z.exe") #9 20 0 0

完！
