I disagree this python version is as readable and here’s why. It’s about as many characters but more complex. The Kotlin version performs several distinct actions, each being clear to its purpose. These actions have the same syntax (eg requires less parsing effort). The Python version mixes at least 4 different language syntax/features, being list comprehension, if special form in the list comprehension, keywords, and lambda functions.

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.
