从思维模型到 DSA 模式的 Python。12 节课，5 个阶段 — 每个代码块都通过 Pyodide 在你的浏览器中运行。
Learn Python by editing live examples in the browser, from first ideas to data-structure patterns.
A browser-based Python curriculum organized into ordered phases of lessons, from mental model up through data-structures-and-algorithms patterns. Every code block on every lesson page is editable and runnable in place via Pyodide, so the runtime is the same CPython semantics you'd get locally, just compiled to WebAssembly.
The Pyodide runtime is ~10 MB and downloads lazily on the first Run click, then caches for the session. The site started as a Rust+WASM curriculum before being ported to Astro+MDX in May 2026; the REPL was retrofitted onto every lesson a few days later. Start at lesson 1 or jump into the glossary.
