Problem

Most Python tutorials explain variables as boxes. I wanted practice that fits a software-design student: short challenges whose explanations use architecture and data-structure vocabulary. It also had to run anywhere, without installing anything.

What it does

  • Lessons and challenges with real CPython in the browser (Pyodide). Your code runs and is checked against tests.
  • Gamified: XP, ranks and progress per local profile, with synthesised sound effects.
  • Fully trilingual, English / German / Japanese, in a Japanese sumi-e dark theme.

How

  • A plain static site: classic <script> tags instead of ES modules, so it even works from file://.
  • Pyodide (~10 MB) and CodeMirror load from a CDN once and are then cached, so repeat visits work offline.
  • No backend: profiles and progress live in the browser. Deployed on Vercel without a build step.
