We spent the last few weeks compressing our book, Python Polars: The Definitive Guide (nearly 500 pages), down to a two-page cheatsheet. It's a highly lossy compression, but hopefully a useful one! Besides the PDF, there's also

You can probably get these sets second hand. I just revived a bricked one (hah!) myself. Had to use the Lego software to update the firmware for that, which only runs on Windows 7, 8, and 10. I just got NXT-Python [1] working on macOS via a

Author here. Worth pointing out that the discussion from Sept 19 2013 is actually about a blog post, which predates the book. It's because of the amount of feedback it got on HN that I wondered whether this topic could be turned into a

I also thought it was made with TikZ (which is a compliment). I used TikZ for my thesis: https://jeroenjanssens.com/phd/ and same thing here, the code is a mess.

Luckily our book will also be available in hard copy so you can digest all that hard-won knowledge in an offline manner :)

Ritchie Vink (the creator of Polars) deliberately decided not to write a book so that he (and his team) can focus full time on Polars itself. Thijs Nieuwdorp and I are currently working on the O'Reilly book "Python Polars: The Def

My book Data Science at the Command Line has a chapter about this that scratches the surface and lists some resources in case you want to dive deeper [1]. I can also recommend checking out packages such as Rich [2] and Click [3], if only to
