General domain of usage
Web scraping

Welcome to the course! Today, you will start exploring how **web scraping** works.


**Web Scraping** is a process used to automatically extract information from websites. For instance, you can use it to compare prices on various platforms or gather data about stocks.

Definition

There are numerous methods in python for extracting data. Let's compare the most popular libraries for web scraping: `requests`, `BeautifulSoup`, `lxml`, and `Selenium`.

Throughout this course, the primary focus will be on the first two libraries. However, `selenium` and `lxml` are also powerful tools:

* `selenium` enables **JavaScript** support, allowing interaction with dynamic fields and menus;
* `lxml` simplifies working with both **HTML** and **XML** files.
