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 )
