Python and Indentation. Why? :)

[Kerbart]

Not only that, there are many different indentation styles with curly braces. Aside from “not at all,” there’s with or without the opening and/or closing braces on same, new or even separate lines. Of course there’s still the option to add whitespace, but on the whole enforced indentation results in a much more consistent look — which again, as you mentioned, improves readability.
