List all subdirectories on given level

Question

I have backup directory structure like this (all directories are not empty):

/home/backups/mysql/
    2012/
        12/
           15/
    2013/
        04/
         


        

Answer 1

from glob import iglob

level3 = iglob('/home/backups/mysql/*/*/*')

(This will skip "hidden" directories with names starting with .)

If there may be non-directories at level 3, skip them using:

from itertools import ifilter
import os.path

l3_dirs = ifilter(os.path.isdir, level3)

In Python 3, use filter instead of ifilter.
