It should also be noted that Python would allow a more functional style, possibly leaving out the list comprehension.
It does contain a generator expression though, which is the same as a list comprehension in general structure, but slightly more confusing because it doesn't have the relationship to lists that square brackets in a list comprehension would have given it.
My point, though, was that not being able to tell the difference was a key "tell" that the comment author was not very familiar with Python — in some contexts, that would tend to undermine credibility in their comment (and then it would be rude to point it out), but in this context, it probably makes their opinion more objective.
The map filter chaining is obviously simpler, but python code is not that difficult and it's a no brainer task anyway.
On top of the lessened readability, the Kotlin version makes it very easy to add, subtract, or comment out lines/actions which really helps when debugging. The Kotlin version is almost identical in structure to how you’d do it in Rust, Elixir, etc.
