Python os.walk: how to delete directories after its sub-directories are all deleted - directory

Question

I have a multi-layer directory. I want to start from the lowest level directories and delete all empty directories. My current code doesn't delete higher-level directories that become empty after their sub-directories are all deleted becuase os.walk supposedly doesn't update the path? How should I modify it so that it updates root each time?
for root, dirs, files in os.walk(starting_directory, topdown=False):
if not files and not dirs:
shutil.rmtree(root)

This script will do the job. Goes to the very bottom of a directory tree... is the directory empty? yes? then delete and goes up from there. Good for cleaning empty folders.
#!/usr/bin/python

import os
for root, dirs, files in os.walk(".", topdown=False):
for name in files:
print(os.path.join(root, name))
for name in dirs:
print("...in for name in dirs", name)
print(os.path.join(root, name))
if len(os.listdir(os.path.join(root, name))) == 0:
print("Directory is empty... deleting")
os.rmdir(os.path.join(root, name))
else:
print("Directory is not empty")
