TL;RD; Functional Python on top of Flutter

From https://github.com/flet-dev/flet:

" Deliver to any device Deploy Flet app as a web app and view it in a browser. Package it as a standalone desktop app for Windows, macOS and Linux. Install it on mobile as PWA or view via Flet app for iOS and Android."

From https://coconut.readthedocs.io/en/latest/HELP.html:

"Specifically, Coconut adds to Python built-in, syntactical support for:

pattern-matching

algebraic data types

destructuring assignment

partial application

lazy lists

function composition

prettier lambdas

infix notation

pipeline-style programming

operator functions

tail call optimization

where statements"

A great choice of companion language to your Python stack would be Nim: https://nim-lang.org/ (not necessarily ML-inspired) but extremely productive and extremely fast. Bonus, v1.0 is right around the corner for Nim. If you're willing to venture out to a place with an evolving scientific ecosystem, Nim is a great choice to do scientific computing as part of a CPython stack (easy integration both ways since Nim compiles to both C/C++).
