The os.walk() Method

The os.walk() method generates the subdirectories and files in a given path as a 3-tuple of a path string with subdirectory list and filename list.

import os

for path, directories, files in os.walk(os.getcwd()):
    for directory in directories:
        print(os.path.join(path, directory))
    for file in files:
        print(os.path.join(path, file))

Output:

... <all subdirectories and files in the current working directory>
