How to list only down-most directories in Python?

Question

import os

for dirpaths, dirnames, filenames in os.walk(mydir):
    print dirpaths

gives me all (sub)directories in mydir. How do I get only the directories at the very bottom of the tree?

Answer 1

This will print out only those directories that have no subdirectories within them

for dirpath, dirnames, filenames in os.walk(mydir):
    if not dirnames:
        print dirpath, "has 0 subdirectories and", len(filenames), "files"

Answer 2

Like this?

for dirpaths, dirnames, filenames in os.walk(mydir):
    if not dirnames: print dirpaths

Answer 3

import os

mydir='/home/'
print [dirpaths for dirpaths, dirnames, filenames in os.walk(mydir) if not dirnames]
