Python people legitimately upset they can't write every function like this now:

def func(data, *kwargs): """data: the data. kwargs: other data."""

# returns the result

Technically, Python typing is more verbose than Java because it uses more tokens. Compare these:

    Python: def foo(x: int, y: int) -> int:  return x + y

    Java: int foo(int x, int y) { return x + y; }

Python uses colons and arrows while Java uses positions to encode where the type should go.
