## Overview

This repository is a Python 3 teaching collection, not a runtime application. Learners use Jupyter to explore interactive lessons and exercises, or read the HTML materials in a browser. The README also documents Binder as an optional way to open the notebooks in a cloud Jupyter session. The tree and README establish these learning paths; sampled source only covers a notebook-to-HTML conversion utility, which is excluded as delivery tooling.
