Summary

In this chapter, we began by installing the regular expression library, and we talked a little bit about the regular expression syntax, such as how the dot matches any one character and the pipe allows us to match any expression to the left or the right of the pipe. We talked about atoms and atom modifiers. We also talked about character classes at length. We used regular expressions within a CSV file and an SQLite3 database. You should always thoroughly test your regular expressions, as they tend to be difficult to debug. With that, we will be discussing data visualization in the next chapter.
