os.walk() - os

             
The method walk() generates the file names in a directory tree by walking the tree either top-down or bottom-up.


top -- Each directory rooted at directory, yields 3-tuples, i.e., (dirpath, dirnames, filenames)
topdown -- If optional argument topdown is True or not specified, directories are scanned from top-down. If topdown is set to False, directories are scanned from bottom-up.
onerror -- This can show error to continue with the walk, or raise the exception to abort the walk.
followlinks -- This visits directories pointed to by symlinks, if set to true.

Syntax

os.walk(top[, topdown=True[, onerror=None[, followlinks=False]]])

Example

# !/usr/bin/python

import os
for root, dirs, files in os.walk(".", topdown=False):
    for name in files:
        print(os.path.join(root, name))
    for name in dirs:
        print(os.path.join(root, name))
