A summary of how Python iterates through the directory

This article summarizes Python's way of traversing a directory. Share to everyone for your reference, as follows:

Method one uses recursion:

"" "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:    passwalkdir (os.environ[' TEMP '], Deletedir, DeleteFile)

Method Two:

Import OS, Statdef 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:    passwalkdir (os.environ[' TEMP '], Deletedir, DeleteFile)
