Remove empty folders (Python)

Question

This is the folder tree:

FOLDER\\
       \\1\\file
       \\2\\file
       \\3\\
       \\4\\file

The script should scan (loop) for each folder in FOLDER and check if the sub-folders are empty or not. If they are, they must be deleted.

My code, until now, is this:

folders = ([x[0] for x in os.walk(os.path.expanduser('~\\Desktop\\FOLDER\\DIGITS\\'))])
folders2= (folders[1:])

This scan for folders and, using folders2 begin from the firs folder in DIGITS. In DIGITS there are numbered directories: 1,2,3,4,etc

Now what? Tried using os.rmdir but it gives me an error, something about string. In fact, folders2 is a list, not a string, just saying...

Answer 1

Not sure what kind of error you get, this works perfectly for me:

import os

root = 'FOLDER'
folders = list(os.walk(root))[1:]

for folder in folders:
    # folder example: ('FOLDER/3', [], ['file'])
    if not folder[2]:
        os.rmdir(folder[0])
