Suppose I have a collection of strings defined as a StrEnum:

class ValidNames(StrEnum):
    OLLY = auto()
    ADAM = auto()
    ANNA = auto()

I want to define a class, ideally with Pedantic (for type verification and conversion) that looks like this:

class Assignment(pydantic.BaseModel):
    olly: int = 0
    adam: int = 0
    anna: int = 0

And I want to be able to take external JSON data like this:

external_data = {"olly": 14, "anna": 3}
this_assignment = Assignment(**external_data)

However, I don’t want to have to explicitly define the fields of Assignment; I want it to be defined by the values of ValidNames because I don’t want to change two bits of code every time the members of ValidNames change (or are added or deleted), and for other reasons. Is there a way to do this? With or without Pydantic?
