Selenium

Selenium is a popular library primarily used for automating web browsers. It was designed for testing websites, but today it has become a popular tool for scraping websites that rely on JavaScript. 

One of the main reasons why you should use Selenium for web scraping is its ability to handle dynamic content. Additionally, if you want to scrape websites like Amazon or eBay, Selenium is a good option as it has packages like selenium-stealth that help to avoid IP address detection.

The library allows you to control a web browser programmatically. You can mimic actions like clicking buttons, filling out forms, and even taking screenshots. Selenium supports major browsers like Chrome, Firefox, Safari, and Edge. Also, you can use it with different programming languages like Python, Java, Ruby, and JavaScript.

However, Selenium has a steep learning curve. What’s more, it runs a full browser instance, so it uses a lot of computing resources.
