Use annotations for schema description.

class Response(Schema):
    a: float
    b: Optional[dt.datetime]

When annotations not enough

class Response(Schema):
    c: str = fields.Email()

And IDE autocomplete cause now your data is instances of relevant classes

class User(Schema):
    name: str

class Response(Schema):
    user: User

response: Response = Response.load({"user": {"name": "Vasya Pupkin"}})
