Question

How would you delete in Python all files in directory /tmp/dir and all its subdirectories that have extension .txt or .mp3?

Answer 1

You just need to use os.walk to traverse recursively a directory and os.remove when you find a file whose name matches your requirements.

Note that os.walk returns on one hand file names and, on the other hand, a root directory. Hence, for the os.remove to work you’ll need to create the full filename with os.path.join.
