Based on https://docs.python.org/2/library/abc.html, it seems abstract classes are available starting in version 2.6 (the top says "New in version 2.6.")
However, I cannot
from abc import ABC, abstractmethod using python 2.7.16 as it produces the error:ImportError: cannot import name ABC but I can with python3+. So is abc not available for python 2.X?
