Thanks for making this!

Note: I was carefully reading along and well into the third notebook before I realized that the code sections marked "TODO" were actual exercises for the reader to implement! (And the tests which follow are for the reader to check their work.)

This is a clever approach. It just wasn't obvious to me from the outset.

(I thought the TODOs were just some fiddly details you didn't want distracting readers from the big picture. But in fact, those are the important parts.)

Great feedback, I didn't even think about that the TODOs could be indeed confusing! I updated the instructions in the README.md calling them out explicitly as the coding sections to be completed. Thanks again!
