Based on a really old edition before it was renamed "Think Python" eons ago. The "interactivity" is pretty much quiz questions that test that you read the chapter at all. Looks like it has some pythontutor integration too, but not much. Layout feels like they gave up on the CSS halfway through.

You're better off going here instead, interactive or no: https://allendowney.github.io/ThinkPython/

The third edition (at your link) is interactive, each chapter is available as a Jupyter notebook. Though to run it on Google Colab (where it is available by default, but you can download it) you do have to log into a Google account.
