There’s just not enough room in this book to show you everything you might possibly need to know. So, here’s our list of the top ten things we didn’t cover that you might want to learn more about next.

Throughout this book, we have very stubbornly resisted writing code in the most correct Python Way. “That’s not how a Python programmer would do it,” was a familiar refrain heard from the Head First Programming technical reviewers. Without fail, and with the greatest of respect to our reviewers, we generally ignored this advice.

This is, of course, a very good thing, because the more programmers using a particular language who follow the standard way of doing something, the better.
