os.walk() is you friend! (Don't use os.path.walk() anymore)

"Off the top of my head":

for dir, dirnames, filenames in os.walk(topdir):
    for dir in dirnames:
        do_something_with_subdir(os.path.join(dir, dirname)
    for file in filenames:
        do_something_with_file(os.path.join(dir, filename)
