Setting up a development environment is a very important task, and we just did this! Creating a "Hello World" application is a great way to introduce a new technology to someone. We also did that. At last, we learned how to serve an HTML page and static files, which is pretty much what most Web applications do. You acquired all these skills in this chapter, and I hope the process has been quite easy but fulfilling!

In the next chapter, we add a little sauce to our challenges by getting more adventurous with templates. We'll learn how to use Jinja2 components to create powerful templates that allow us to do more with less typing. See you there!
