[$] Introducing PyScript

In a keynote at PyCon 2022 in Salt
Lake City, Utah, Peter Wang introduced another entrant in the field of
in-browser Python interpreters. The Python community has long sought a way
to be able to write Python—instead of JavaScript—to run in web browsers, and there
have been various efforts to do so over the years. Wang announced PyScript as a new framework, built atop
one of those earlier projects, to allow
Python scripting directly within the browser; those programs have access to
much of the existing Python ecosystem as well as being able to interact
with the browser document object model (DOM) directly.
In addition, he gave some rather eye-opening demonstrations as part of the talk.
