python实例[查询修改文件的属性]

python来获得文件的

通用属性：大小，修改时间等； 去掉文件的readonly属性；

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")

import win32api,win32con

def TestWinFileAttributesIfReadonly(): # This is just for windows.

fattrs = win32api.GetFileAttributes("c:\\python26\\python.exe") #print fattrs

print bool(fattrs & win32con.FILE_ATTRIBUTE_READONLY)

TestWinFileAttributesIfReadonly() #False

def TestWinFileAttributesIfHidden(): # This is just for windows.

fattrs = win32api.GetFileAttributes("c:\\python26\\python.exe") #print fattrs

print bool(fattrs & win32con.FILE_ATTRIBUTE_HIDDEN)

TestWinFileAttributesIfHidden() #False

from win32api import GetFileVersionInfo, LOWORD, HIWORD def get_version_number(filename): # This is just for windows.

info = GetFileVersionInfo(filename, "\\") #print info

ms = info['FileVersionMS'] ls = info['FileVersionLS']

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


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

完！
