python遍历目录的方法小结

本文实例总结了python遍历目录的方法。分享给大家供大家参考,具体如下:

方法一使用递归:

“””
def walkdir( dir, dir_callback = none, file_callback = none ):
for item in os.listdir( dir ):
print item;
fullpath = dir + os.sep + item
if os.path.isdir( fullpath ):
walkdir( fullpath, dir_callback, file_callback )
if dir_callback: dir_callback( fullpath )
else:
if file_callback: file_callback( fullpath )”””
def deletedir( dir ):
print “path”
#os.rmdir( dir )
def deletefile( file ):
try:
print “file”
#os.unlink( file )
except windowserror, e:
pass
walkdir( os.environ[‘temp’], deletedir, deletefile )

方法二:

import os, stat
def walkdir( dir, dir_callback = none, file_callback = none ):
for root, dirs, files in os.walk(dir):
for f in files:
print f
file_path = os.path.join(root, f)
if file_callback: file_callback( file_path )
for d in dirs:
dir_path = os.path.join(root, d)
if dir_callback: dir_callback( dir_path )
def deletedir( dir ):
print “path”
#os.rmdir( dir )
def deletefile( file ):
try:
print “file”
#os.unlink( file )
except windowserror, e:
pass
walkdir( os.environ[‘temp’], deletedir, deletefile )
