During my current projects  I m often passing rear parts of a path to a function and therefore use the Path module  To get the n-th part in reverse order  I m using  from typing import Union from pathlib import Path  def get single subpath part base dir  Union Path  str   n int  - gt  str      if n   0          return Path base dir  name     for   in range n           base dir   Path base dir  parent     return getattr base dir   quot name quot    path   quot  folderA folderB folderC folderD  quot     for getting the last part  print get single subpath part path  0     yields  quot folderD quot     for the second last print get single subpath part path  1    yields  quot folderC quot   Furthermore  to pass the n-th part in reverse order of a path containing the remaining path  I use  from typing import Union from pathlib import Path  def get n last subparts path base dir  Union Path  str   n int  - gt  Path      return Path  Path base dir  parts -n-1     path   quot  folderA folderB folderC folderD  quot     for getting the last part  print get n last subparts path path  0     yields a  Path  object of  quot folderD quot     for second last and last part together  print get n last subparts path path  1     yields a  Path  object of  quot folderc folderD quot   Note that this function returns a Pathobject which can easily be converted to a string  e g  str path

You could do   gt  gt  gt  import os  gt  gt  gt  os path basename   folderA folderB folderC folderD     UPDATE1  This approach works in case you give it  folderA folderB folderC folderD xx py  This gives xx py as the basename  Which is not what you want I guess  So you could do this -    gt  gt  gt  import os  gt  gt  gt  path     folderA folderB folderC folderD   gt  gt  gt  if os path isdir path           dirname   os path basename path    UPDATE2  As lars pointed out  making changes so as to accomodate trailing        gt  gt  gt  from os path import normpath  basename  gt  gt  gt  basename normpath   folderA folderB folderC folderD      folderD
