Python + pyscript + WebAssembly: Python Web Apps, Running Locally with pyscript

Can we build a pyscript (client-side Python) web app that loads super quick and doesn't lag during startup? Could we create one that looks like a regular web app rather than just an embedded Jupyter notebook or data science experience?

The answer is YES! And you'll learn how to build exactly that in this video. No pyscript or pyodide experience necessary. Just lovely Python apps running locally in your macOS dock or Windows taskbar.
