What is web scraping ?
Let's say your boss at work gave you a task where he wants you to extract about 1000product from a website, structure the data and save it to a database, would you copy paste manually all the product details from the product name, url and price ? I can imagine you would work days and nights and you wont finish the task, so this is where web scraping shines. So web scraping, or web harvesting or web data extraction is like writing a script that will automate data extraction from websites in a matter of minutes !.

Yes, each section has an assignment included to it, this will help to get your hands dirty and by the end of each section after doing the assignment included you will feel more confident and comfortable with web scraping.
Why LXML and not BeautifulSoup ?
LXMLis a lightweight HTMLparser even the most popular web scraping framework (Scrapy) is built on the top of LXML, BeautifulSoup is a little bit overloaded with the number of functions exposed to us, it has more functions to use, yes that's right ! however in Web Scraping most of the time we use XPath and CSSSelectors to navigate and select what to scrape from the HTMLweb page (tree) so there is no need to learn about new functions and wasting all that time to familiarize yourself with the BeautifulSoup API and the internal architecture, in addition to all of that LXMLin terms of performance is way better than BeautifulSoup.
