Dynamically Detect Variable Annotations

[EricScottN]

Not sure this exists as a flag or combination of flags, but I was wondering if there was a way to automatically detect duplicate class variables and extract/replace them with variable annotations at the top of the module. For example, assume the following two classes were created from a json file:

class ClassA(BaseModel):
    abbrev: str
    score: int
    place_name: Annotated[str, Field(alias='placeName')]

class ClassB(BaseModel):
    id: int
    market: str
    place_name: Annotated[str, Field(alias='placeName')]

What I would like to see instead:

PlaceName = Annotated[str, Field(alias='placeName')]

class ClassA(BaseModel):
    abbrev: str
    score: int
    place_name: PlaceName

class ClassB(BaseModel):
    id: int
    market: str
    place_name: PlaceName
