Interesting, so it seems micropython 1.9.4 targets Python 3.4. Not that one'd use the calculator for any common Python development, but it's a shame since most Python libraries target at least Python 3.6.

>but it's a shame since most Python libraries target at least Python 3.6.

Why would that matter? Would Micropython be able to run "most Python libraries" anyway?

Pure python ones, yes.

Even pure python ones are not all usable, as "it includes a subset of the standard library" (so a pure python library that uses some standard library API not in the subset wont be usable).

Does python have many polyfills available, like javascript does?

I'm sure you'd run out of space before too long, but it'd probably improve usability.

That's _very_ old; v1.9.4 was released May 2018...

Anything that qualifies as “very old” after a mere five years arguably shouldn’t be made part of a physical appliance anyway. That being said, I would disagree with that qualification here.
