python遍历目录的方法小结

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 )
