Step 4: Digging deep into Beautiful Soup further

list(soup.children)soup = BeautifulSoup(page.content, 'html.parser')

Step 5: Exploring page structure with Chrome Dev tools and extracting information

page = requests.get("https://en.wikipedia.org/wiki/Main_Page")
soup = BeautifulSoup(page.content, 'html.parser')
object = soup.find(id="mp-left")
items = object.find_all(class_="mp-h2")
result = items[0]
