Python is now a full browser client language w/ PyScript:

> **[Pyscript.net](https://pyscript.net/)**
>
> Run Python code in your HTML.

So again I couldn’t resist converting my previous RapydScript sketch “Self Avoiding Walk II” to PyScript.

I’ve also added Python type hints to the whole code:

> **[PEP 483 – The Theory of Type Hints | peps.python.org](https://peps.Python.org/pep-0483/)**
>
> Python Enhancement Proposals (PEPs)

All 3 JS Processing flavors run on PyScript just like CoffeeScript & RapydScript previous versions:
