Pyfun Playground

Pick an example and tweak it on the left; the readable Python it compiles to appears on the right, type-checked live by the real compiler running in your browser via WebAssembly. Hit Run to execute that Python — CPython itself, in the browser (Pyodide). No server, no runtime library.
