Can I override type of an existing attribute by `__getattribute__` method?

I wrote a simple code where I override the __getattribute__ method so that it always returns an empty string. But Pyright doesn't understand this and complains "int" is not assignable to "str"

My code:

import typing as ty from dataclasses import dataclass class MetaModel(type): def __new__(cls, name, bases, attrs): return super().__new__(cls, name, bases, attrs) def __getattribute__(cls, name: str, /) -> str: if name.startswith("_"): return super().__getattribute__(name) return "" class BaseModel(metaclass=MetaModel): def __getattribute__(self, name: str) -> str: return "" @dataclass class Model(BaseModel): field: int = 0 if __name__ == "__main__": model = Model() field1: str = model.field # "int" is not assignable to "str" field2: str = Model.field # "int" is not assignable to "str" field3: str = Model.undefined_field # it`s fine ty.reveal_type(field1) # str ty.reveal_type(field2) # str ty.reveal_type(field3) # str
