Learning Python Offline with a PWA

Why AI, Why Offline?

I’ve always wanted to get back to basics and truly understand Python’s core concepts without being tethered to a network. When my family and I started planning a trip I realised I’d be offline for a bit and I saw an opportunity. Why not build a Progressive Web App (PWA) that teaches Python fundamentals entirely client-side, even when you’ve got zero signal?

Building Skulpt Locally

Rather than pulling Skulpt from a CDN, I cloned the public repositories, ran the build process locally (with a quick nvm switch to Node 16 to avoid OpenSSL issues), and bundled the minified skulpt.min.js and skulpt-stdlib.js into dist/. That way the entire runtime ships with the app—no internet required.

Technical Highlights

• Offline-first: A service worker precaches every HTML, CSS, JS and Skulpt asset.
• Single page layout: Collapsible sidebar for navigation; main pane for lessons, code editors and quizzes.
• Interactive code: Editable Python snippets powered by Skulpt, with real-time output.
• Progress tracking: Quiz results saved in localStorage, so you can pick up where you left off.
• Lightweight styling: Mobile-first, plain CSS, no frameworks, so it’s lightning fast and fully functional offline.

Conclusion

Whether you’re a digital nomad, a commuter or just someone who likes to tinker offline, this PWA lets you learn Python wherever you are. Give it a spin on your device, just add it to your home screen and you’re good to go.
