As you probably know, HTML tags are nested within other tags. They form an **inheritance tree**, where nested tags are "children" of other tags:

Here the inheritance goes from top to bottom. For example, the two `p` elements are children of the same parent `div`, `head` and `body` elements are descendants (second generation) of `html`.

In the future, it will be essential to understand the structure of the HTML file to write paths to the tags we want to extract; however, we will consider methods that can be used by searching tags or attributes.

Web Scraping is a process that can be used to automatically extract information from websites. This course will help you to get the data from sources and transform it to the DataFrames using various libraries!

Here we will explore the structure of the HTML file, how to load it and work with the data in the file.

Learn how to extract the data more comfortably with the BeautifulSoup library.

Explore how XPath and CSS Selectors can be used to locate web elements without id, class, or name.

Here we will learn how to convert tables into the DataFrame for the following analysis.
