Python playground

Write and run Python here. Everything executes locally in your browser via Pyodide — no signup, no server, and your code is saved to this browser between visits. Cmd/Ctrl+Enter to run.

What runs here

Full CPython standard library — asyncio, dataclasses, re, json, collections, itertools, and more.
Pure-Python packages via micropip.install("package").
Top-level await (Pyodide runs your code as a coroutine).
Anything that requires a browser: fetch via pyodide.http, DOM access via import js.

What doesn't

Native extensions Pyodide has not built (e.g. torch, tensorflow). You'll see an ImportError and can pivot to a pure-Python alternative.
File I/O to your real disk — Pyodide has an in-memory virtual filesystem.
