11. Iterate Over Root Path

Write a Python program to iterate over a root level path and print all its sub-directories and files, as well as loop over specified dirs and files.

Sample Solution:

Python Code :

import os
print('Iterate over a root level path:')
path = '/tmp/'
for root, dirs, files in os.walk(path):
 print(root)

Sample Output:

Iterate over a root level path:
/tmp/

Python Code :

import os
print('Loop over dirs and files:')
path = '/tmp/'
for root, dirs, files in os.walk(path):
       print(root)
       for _dir in dirs:
           print(_dir)
       for _file in files:
           print(_file)

Output:

Loop over dirs and files:
/tmp/
