The "bad" Python code in that example is perfectly fine. I'm not a Python programmer but I can read Python a little bit, and the example uses basic programing concepts like string splitting and array ranges. If you don't understand that, multiple smaller lines won't help you, because you just don't know what you are doing. In addition, that code example is easily testable. Testability is more important than readability in modern programs that follow modern CI/CD principles -- and the readability is not really that bad either. Also, modern debuggers don't have issues with nested/lambda statements like these. If the article's author had a legitimate bone to pick, they would have better examples.
