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 on the title to see a description, or click the title to view on github, or click one of the letters in the left column to launch the notebook on Colab, Deepnote, Mybinder, Sagemaker, or NBViewer.
