In this chapter, we learned about regular expressions and their implementation by using the re Python library.

So far, we've learned about various scraping-based tools and techniques. Regex can provide more flexibility when it comes to extraction tasks and can be used with other tools. 

In the next chapter, we will be learning about further steps and topics that could be beneficial in a learning context, such as managing scraped data, visualization and analysis, and an introduction to machine learning and data mining, as well as exploring some related resources.
