How does os.walk() work in python ?

OS.walk() generate the file names in a directory tree by walking the tree either top-down or bottom-up. For each directory in the tree rooted at directory top (including top itself), it yields a 3-tuple (dirpath, dirnames, filenames).

  • root : Prints out directories only from what you specified.
  • dirs : Prints out sub-directories from root.
  • files : Prints out all files from root and directories.

        print root
        print dirs
