Python Initializing and typing at the same time

Question

Can I initialize an empty dictionary and typing it at the same time?

For example something like that, however I don't think this is proper.

self.groups: Dict[str, Group]
self.groups = dict()

`groups` should be type annotated at the class level, to follow python typing convetions, although it isn't required. — juanpa.arrivillaga, Sep 24 '20 at 16:14

Yes, simply insert the type hint after the variable name in the assignment.

self.groups: Dict[str, Group] = dict()
