Python Initializing and typing at the same time

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()
Solution

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

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