“my observation that API's in Python tend to much nicer and much less verbose” I trust you don’t mean Python’s stdlib APIs, which are an inconsistent mess. (Python 3 did very little to improve this, unfortunately.) There’s also a lot to be said for only having to annotate interfaces once and once only, and have that information reliably applied at compile/run time (depending on language) and across all documentation and tooling too. Docstring schemes are the pits (though most typed languages are little/no better than untyped ones here).
