Python for frontend devs — add a backend without leaving the browser

You already know event loops, JSON, fetch, async/await. Python isn't a new language — it's the same patterns with different syntax. The shortest path from frontend to fullstack starts here.

Most 'Python for JavaScript developers' content treats you like a beginner — variables, if/else, loops. You don't need that. You need to know that f-strings replace template literals, that comprehensions are like .map().filter(), that decorators are like higher-order functions, that pip is what npm pretends to be. You need the differences, not the basics.

This track is 170 Python Foundations lessons (skim the first 30 in an afternoon) plus 101 FastAPI lessons that map 1:1 to the Express/Hono APIs you've already written: routes, middleware, request validation (Pydantic vs Zod), auth (JWT, cookies), Stripe webhooks, deploys. Each lesson has an AI tutor that translates a Python idiom into 'this is what useState would do in your stack.' By week 4 you ship a real FastAPI service backing your existing React frontend. By week 8 you stop being 'a frontend dev' on LinkedIn.
