Bug description

from abc import ABC, abstractmethod
from typing import TypeVar

from src.internal.core import entities, dtos


Entity = TypeVar("Entity")
CreateDto = TypeVar("CreateDto")
UpdateDto = TypeVar("UpdateDto")


class BaseDao[Entity, CreateDto, UpdateDto](ABC):
    @abstractmethod
    def create(self, *_, **kwargs: CreateDto) -> Entity | None:
        return NotImplemented

    @abstractmethod
    def find_all(self) -> list[Entity] | None:
        return NotImplemented

    @abstractmethod
    def find_by_id(self, uid: str) -> Entity | None:
        return NotImplemented

    @abstractmethod
    def update(self, uid: str, **kwargs: UpdateDto) -> Entity | None:
        return NotImplemented

    @abstractmethod
    def delete(self, uid: str) -> None:
        return NotImplemented


class UserDao(BaseDao[entities.User, dtos.CreateUserDto, dtos.UpdateUserDto]):
    pass

Pylint output

Value 'BaseDao' is unsubscriptablePylint[E1136:unsubscriptable-object](https://pylint.readthedocs.io/en/latest/user_guide/messages/error/unsubscriptable-object.html)

Expected behavior

Is this my code wrong, or pylint is not detecting the code correctly?
If I add more methods to UserDao, the error's gone. However, I just want to prevent redundant abstract classes.

Thanks for the report. Will be closing as a duplicate of a slimmer example reported and triaged in #9406
