"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.
Some programs are in Jupyter (.ipynb) notebooks, some in .py files. For each notebook you can:
- Click on co to run the file on Colab
- Click on dn to run the notebook on DeepNote
- Click on my to run the notebook on MyBinder
- Click on nb to view the notebook on NBViewer
- Click on the title to view the notebook on github.
