It is quaint how there is supposed to be an "idiomatic python" just as mypy, "pattern statements", walrus operators, etc. are being added.

"Idomatic python" is dead, and lives now only as a pretty dumb ideology which states: everything must be phrased as a naively-typed naively-imperative program. Python is being made, retroactively, a bad imperative programming language: largely because its creator always thought that's what he'd made (he is wrong).

It's a great tragedy "pythonic" has become this: a back-reaction against the times (of increasing adoption of functional programming driven by increasing data-transformation needs).
