How to specify argument type in a dynamically typed language, i.e. Python?

Question

Is there any such equivalent of Java

String myMethod (MyClass argument) {...}

in Python?

Thank you, Tomas

Python 3.x has function annotations where you can declare argument and return types:

def myMethod(argument: MyClass) -> str:
   ...

But currently Python does nothing with them, they serve as documentation only.
