Python is actually strongly typed and dynamically typed, not untyped. Even Javascript is not untyped -- it is weakly typed. (not that any of these concepts have watertight definitions, but there's a general notion of what they mean)

That said, having used a statically typed language for large scale development, I've come to prefer for static typing even as a Pythonista. Mypy is a partial solution for this -- we'll see what the uptake on that is.
