Before using Beautiful Soup, you need to install it. You can do this by running the following command in your terminal:

pythonCopy codesoup = BeautifulSoup(html_content, 'html.parser')

Step 5: Extract the Data

Finally, you can extract the data you want from the parsed HTML content. You can do this by using the various methods provided by Beautiful Soup, such as find_all() to find all instances of a specific HTML tag, or select() to find elements based on CSS selectors.

pythonCopy code# Extract all links from the HTML content
links = soup.find_all('a')

# Extract the text content of all paragraphs
paragraphs = soup.select('p')
text_content = [p.get_text() for p in paragraphs]
