Questions tagged [os.walk]

`os.walk()` is a Python function which serves to walk a directory tree.

With os.walk() you can walk a directory tree and get, for each of the subdirectories, a list of file names.

A simple example goes like

import os
for root, dirnames, filenames in os.walk('.'):
    for filename in filenames:
        print os.join(root, filename)
