Start by importing the Requests library and making a simple GET request to the URL -we chose because it has a straightforward HTML structure and will allow us to demonstrate the potential of Beautiful Soup easily. Since we are using Python for our requests, we need a third-party HTTP library, and we will use Requests. The server responds by sending the HTML content of the web page.

It is possible to carry out web scraping tasks in many programming languages with different libraries, but using Python with the Beautiful Soup library is one of the most popular and effective methods. Step 3: Copying the text inside the target tags, producing the output in the format previously specified in the code. Step 2: Filter the page’s HTML to look for the desired H3 tags. Step 1: Send a request to the server to download the site’s content. We would write code for a scraper that looks specifically for that information. The code then downloads the page, only extracting the elements of the page defined initially in the crawling job.įor example, let’s say we are looking to target data in H3 title tags.
