Python 2.7 Combine abc.abstractmethod and classmethod

Question

How do I create a decorator for an abstract class method in Python 2.7?

Yes, this is similar to this question, except I would like to combine abc.abstractmet

Answer 1

You could upgrade to Python 3.

Starting with Python 3.3, it is possible to combine @classmethod and @abstractmethod:

import abc
class Foo(abc.ABC):
    @classmethod
    @abc.abstractmethod
    def my_abstract_classmethod(...):
        pass

Thanks to @gerrit for pointing this out to me.
