Summary  
This chapter introduces how to implement code for making HTTP requests and parsing HTML/XML document trees using Python libraries—comparing tools like Requests, Beautiful Soup, lxml, and Selenium in terms of speed, ease of use, JavaScript support, and documentation.

General domain of usage  
Web scraping

Welcome to the course! Today, we will begin exploring how __web scraping__ works. 

There are numerous methods in python for extracting data. Let's compare the most popular libraries for web scraping: __Requests__, __Beautiful Soup__, __lxml__, and __Selenium__.

Throughout this course, our primary focus will be on the first two libraries. However, it's worth noting that __selenium__ and __lxml__ are incredibly powerful tools:

- __Selenium__ enables __JavaScript__ support, a programming language that allows developers to interact with dynamic fields and menus;
- lxml facilitates working with both __HTML__ and __XML__ files.
