Dict takes two "arguments", the type of its keys and the type of its values. For a dict that maps strings to integers, use

def doSomething(value: Dict[str, int]):

The documentation could probably be a little more explicit, though.

from typing import Dict

def doSomething(Some_Dict: Dict[str, SomeObject]):

then voila! your IDE will suggest the members of each value (SomeObject) in the dictionary!
