I guess the second approach requires you to be more familiar with Python's concise syntax capabilities while the first is a nice waterfall model that anybody can read. Depends on your team. If you wrote stuff in the second way you would be obstructing, adding friction to less python experienced developers but you would be minimizing the amount of code written. It's hard to say, which is right or wrong here but the opacity of the second approach as you mention adds unpredictability. I honestly think Dart is a very good solution from the culmination of various classical languages we've been using so far with Java and Javascript but there just doesn't seem to be any major FANG company investing in creating something more "modern" with Python. I think it is a testament to Python's accessbility and also the depth it provides for experts as well. I guess the forced indentation is what gets to some developers but its a minor inconvenience.
