bgneal@4	9 Late one night I needed to write some Python code to recursively find empty
bgneal@4	10 directories. Searching online produced some unsatisfactory solutions. Here is
bgneal@4	11 a simple solution that leverages `os.walk`_.
bgneal@4	12
bgneal@4	13 .. sourcecode:: python
bgneal@4	14
bgneal@4	15 import os
bgneal@4	16
bgneal@4	17 empty_dirs = []
bgneal@4	18 for root, dirs, files in os.walk(starting_path):
bgneal@4	19 if not len(dirs) and not len(files):
bgneal@4	20 empty_dirs.append(root)
bgneal@4	21
bgneal@4	22 If you then wish to delete these empty directories:
bgneal@4	23
bgneal@4	24 .. sourcecode:: python
bgneal@4	25
bgneal@4	26 for path in empty_dirs:
bgneal@4	27 os.removedirs(path)
bgneal@4	28
bgneal@4	29 .. _os.walk: http://docs.python.org/2/library/os.html#os.walk
