Sometimes it can be tricky to get the computer to do exactly what you want, and it's a great victory when things finally work. It's tempting to move on to the next task at hand, but often it's better to look back and improve some things.
In this episode Sybren shows some techniques to reorganise code, with the aim of improving the readability & understandability.

Very interesting and useful video. I'll put this in practise with my addons/scripts ^^ thank you again, Sybren
Thanks! Applying these tips and tricks right away!
Cool! +1 for this type of content. Entertaining and useful
I followed along & edited the code in 3.0 Alpha ... It works perfectly (I back up the original ;0)... I'v gotta say, that was the best python tutorial in refactoring I have ever see in two score years. Well played Dr. Stüvel.
@Steven Goodman Thank you so much!
I've just finished all 20 videos and I must say as someone who has been developing software professionally since 1973 this is the best introduction to a programming language for non-developers that I've ever seen. That alone is a difficult accomplishment but to also set the introduction in the context of a fairly complex domain, blender/bpy, is a serious achievement. Well done.
@Marty Fouts Thank you so much!
Hi @sybren I have a slightly unrelated question: some video's are free and some aren't. What criterium is used to decide when a video is free or not?
@Crisp Ness The intro is free as a teaser/trailer. The other free videos were produced during the first covid lockdown, as a gift to the Blender community now sitting at home.
