I am adding type hints to my code base.

In the other module I have this -

To add a type hint, I now have this -
def config_database(db_params: configparser.SectionProxy):
To get this to work, I have to add 'import configparser' at the top of
the module.
I have three separate modules, one for each database, with a subclass
containing the methods and attributes specific to that database. Each
one has a connect() method which receives db_params as a parameter.
Now I have to add 'import configparser' at the top of each of these
modules in order to type hint the method.
This seems verbose. If it is the correct way of doing it I can live
with it, but I wondered if there was an easier way.
Not really. It's like any other name - it needs importing if you're
going to use it.
You can make the hint itself more compact:
from configparser import SectionProxy
.......
def config_database(db_params: SectionProxy):
Or you could be a bit more agnostic:
from typing import Mapping
.......
def config_database(db_params: Mapping):
since I imagine config_database() would accept any kind of mapping
(dicts, etc etc).
