python练习（遍历所有文件夹及文件）

遍历所有文件夹及文件，将exe文件的后缀改为zmp，并将文件设置为隐藏文件或系统文件

from sys import stdin

from os import walk

from os.path import join

import win32api,win32con

for (root, dirs, files) in walk('/'):

#if name in dirs or name in files:

for filename in files:

ext=os.path.splitext(filename)[1]

if(cmp(ext,".exe")==0):

print(filename)

newname=filename.replace(ext,".zmp")

oldpath=root+os.sep+filename

newpath=root+os.sep+newname

print "oldpath:"+oldpath+""

print "newpth:"+newpath+""

try:

os.rename(oldpath, newpath)

win32api.SetFileAttributes(newpath, win32con.FILE_ATTRIBUTE_HIDDEN)

#win32api.SetFileAttributes(newpath, win32con.FILE_ATTRIBUTE_SYSTEM)

except ValueError:

print "Error when rename the file " + oldpath

except NameError:

print "Error when rename the file " + oldpath

except OSError:

print newpath + " The file is already exist!"
