the good news is that all of these fancy features are *optional*. if
you don't know what they're useful for, that probably means you don't
need them yet, so no need to stress that you *have* to learn what they
are as you're learning the language.
at some point, you'll come across a situation where you *wished* that
Python had some feature you wanted, like a function used only in
relation to a class or its instances but don't want to define it as an
external function (@staticmethod) or to have a method where the class
object itself is passed in for you to be able to modify a class value
global to all instances (@classmethod), and to discover that features
*are* there!
