'NavigableString' object has no attribute 'h2'

[RandomCoder]

Good Afternoon!
I have been following a tutorial on beautiful soup by Corey Schafer, but I came across an error when writing the code, and I do not know how I can debug it, considering the code is the same as it is in the video. Could this be due to how old/outdated the information on the video could be? and is there a way to debug this program? Thank you!

from bs4 import BeautifulSoup
import requests

with open('simple.html') as html_file:
    soup = BeautifulSoup(html_file, 'lxml')

for article in soup.find('div', class_='footer'):
    headline = (article.h2.a.text)
    print(headline)

    summary = (article.p.text)
    print(summary)

    print()

Error:
Traceback (most recent call last):
