Custom Websites

We decided to build custom websites for many of the examples used in this tutorial instead of scraping live websites, so that we have full control over the web environment. This provides us stability —– live websites are updated more often than books, and by the time you try a scraping example, it may no longer work. Also, a custom website allows us to craft examples that illustrate specific skills and avoid distractions. Finally, the maintainers of a live website may not appreciate us using them to learn about web scraping and could try to block our scrapers. Using our own custom websites avoids these risks, however, the skills learnt in these examples can certainly still be applied to live websites.
