"An étude (a French word meaning study) is an instrumental musical composition, usually short, of considerable difficulty, and designed to provide practice material for perfecting a particular musical skill." — Wikipedia
This project contains pytudes—Python programs, usually short, for perfecting particular programming skills.
To continue the musical analogy, some people think of programming like Spotify: they want to know how to install the app, find a good playlist, and hit the "play" button; after that they don't want to think about it. There are plenty of other tutorials that will tell you how to do the equivalent of that for various programming tasks—this one won't help. But if you think of programming like playing the piano—a craft that can take years to perfect—then I hope this collection can help.
For each notebook you can hover or click on the title, or click one of the letters in the left column to launch the notebook on Colab, Deepnote, Github, Mybinder, Sagemaker, or NBViewer.

I got the idea for the "etudes" part of the name from this 1978 book by Charles Wetherell that was very influential to me when I was first learning to program. I still have my copy.
