How to iterate over all files in multiple folders with python

Question

I'm trying to iterate over all directories in directory and find all .html files there. So far I've this code:

def find_path():
"""

:return: List
"""
paths = []
for filename in os.listdir(DIRECTORY):
    if filename.endswith('.html'):
        fname = os.path.join(DIRECTORY, filename)
        with open(fname, 'r') as f:
            soup = BeautifulSoup(f.read(), 'html.parser')
            path = soup.select_one('#tree > li > span').contents[-1]
            paths.append(path)
return paths

But it only works if all .html files are in one directory. What I need is to iterate over all .html files in this directory and save it, but for every directory in that directory there are also .html files that I need to have access to. So ideally, I need to open all of these directories in my parent directory and save whatever I need from .html files. Is there a way to do it?

Thanks!

You can use the below sample snippet both #1 or #2 works:

import os
path = "."
for (root, dirs, files) in os.walk(path, topdown=True):
    for file in files:
        if file.endswith(".html"):
            print(root+"/"+file)                #1
            print(os.path.join(root+"/"+file))  #2
