os.walk () in Python

How do I traverse the filesystem in Python? Suppose we have defined a file structure below in our system and want to completely traverse all its branches from top to bottom? 

How does os.walk () work in python?

OS .walk () generates filenames in a directory tree by traversing the tree from top to bottom or bottom to top. For each directory in the tree rooted at the top of the directory (including the top itself), it outputs a 3-tuple (dirpath, dirnames, filenames).

  • dirs: prints subdirectories as root.
  • files: prints all files from root and directories.

# Driver function

import os

if __ name__ = = " __ main__ " :

print root

print dirs

print files

print ’----------------- --------------- ’
