Python in the browser
summary
Demo of PyScript shows runnable Python apps in the browser: a tiny UI toolkit ltk (~600 lines) plus three apps (microlog, a spreadsheet that is “Excel in Python”, and a visual profiler) all packaged to run client-side. Performance tradeoffs are explicit: micropython starts ~100 ms, pyodide/CPython boots ~2 s and with pandas ≈6 s. UI uses a fast micropython frontend and a background Pyodide worker for heavy work, and the examples run successfully in the browser.
