Python OS - using 'os.listdir' to view a directory that returns a list of folders. How do I view the contents of the subfolders?

Question

I have been set a challenge to browse a directory that contains mostly empty folders - the flag(answer) is in one of them. I have used os module to see all the names of the folders - they are all named 'folder-' plus a number between 1 and 200. How do I view what is inside them?

Answer 1

You should use os.walk() instead of litdir() like as

import os
import os.path

for dirpath, dirnames, filenames in os.walk("."):
    for file in filenames:
        print(file)
