PyScript - Writing a Python application in the browser
summary
Demo shows a real to‑do web app built with PyScript and the LTK UI library running in the browser, importing Python packages like Folium and pandas in‑browser, using two WebAssembly VMs so small tasks use MicroPython startup ~40 ms while heavier work runs in a worker on Pyodide ~1 s startup and ~3–4 s for pandas+matplotlib, calls out to web JS APIs and to OpenAI/DALL·E for suggestions and images, and deploys as a static site (pyScript.com, GitHub Pages, or any web host).
