Explanation of the Code

Imports: We begin by importing requests for HTTP requests and BeautifulSoup for HTML parsing.

Define the URL: We specify the URL of the HTML page that contains the link we want to extract.

Make a GET Request: We send a request to the URL and store the response content.

Parse the HTML: After obtaining the content, we create a BeautifulSoup object to parse the HTML.

Select the Link: We use the select_one method with a custom CSS selector that targets the <a> tag containing the text "Summary".

Construct the Full URL: Finally, we concatenate the base URL with the extracted href to get the complete link.

The Output

When you run the code, you'll obtain the following output:
