How to delete recursively empty folders in Python3?

os.walk accepts optional topdown parameter (default: True).

By providing topdown=False, you can iterative from child directories first.

def remove_empty_dirs(path):
    for root, dirnames, filenames in os.walk(path, topdown=False):
        for dirname in dirnames:
            remove_empty_dir(os.path.realpath(os.path.join(root, dirname)))
