David Beazley is a gem. There are 2 subsequent parts to this one, if anyone's interested, they can be found on the "Tutorials" page: https://www.dabeaz.com/tutorials.html https://www.dabeaz.com/tutorials.html Part 1) Generator Tricks for Systems Programmers (what this post links to) Part 2) A Curious Course on Coroutines and Concurrency Part 3) Generators: The Final Frontier Another tutorial I'd recommend -- among my personal favorite -- is "Python 3 Metaprogramming" (also at the URL I included above) Even if you're not interested in the Python programming language, I'd still recommend having a look at his tutorials and talks; the quality of his work, and especially his delivery, make it all enjoyable.
