Python: abstract property type validation

Question

I'm wondering, what is the best practices to handle abstract property type validation?

from abc import ABC, abstractmethod

class Base(ABC):

    @property
    @abstractmethod
    def name(self):
       """
       :type str
       """
       pass

class MyClass(Base):
    name = 1    # TypeError

Answer 1

Use __init_subclass__. You don't name to be a property at all, abstract or otherwise.

class Base:

    def __init_subclass__(cls, *args, **kwargs):
       super().__init_subclass__(**kwargs)
       if not isinstance(cls.name, str):
           raise TypeError(f'{cls.name} is not a string value')


class MyClass(Base):
    name = 1
