hint: if you're not sure what's going on in your program, adding
a print statement or two is an easy way to figure it out. like, say:
for x in listing:
print x
if os.path.isdir(x):
dirs.append(x)
(try this before you continue)

the problem is that os.listdir returns a list of filenames, without
the preceeding directory name. you can add an os.path.join
for x in listing:
x = os.path.join(directory, x)
if os.path.isdir(x):
dirs.append(x)
or use the glob module instead:
listing = glob.glob(os.path.join(directory, "*"))
hope this helps!
