In this example, we used the BS4 library to parse static HTML for us. Beautiful Soup is an invaluable library for dealing with occasionally messy HTML, but when it comes to large scales and dynamic pages, it simply won't suffice. For production scraping in large quantities, perhaps on a regular basis, it is a good idea to utilize the Scrapy (https://scrapy.org/) package. Scrapy is an entire framework for downloading HTML, parsing data, pulling data, and then storing it. One of its killer features is that it can run asynchronously – for example, while it is waiting for one page to load, it can switch to processing another, automatically. Because of that, Scrapy's scrapers are significantly faster on large lists of websites. At the same time, its interface is more expressive for a developer, as it is explicitly designed for scraping.
