Abstract methods in Python

I am having trouble in using inheritance with Python. While the concept seems too easy for me in Java yet up till now I have been unable to understand in Python which is surprising to me at least. I have a prototype which follow: class Shape(): def __init__(self, shape_name): self.shape = shape_name class Rectangle(Shape): def __init__(self, name): self.shape = name In the above code how can I make an abstract method that would need to be implemented for all the subclasses?
Something along these lines, using ABC import abc class Shape(object): __metaclass__ = abc.ABCMeta @abc.abstractmethod def method_to_implement(self, input): """Method documentation""" return Also read this good tutorial: https://pymotw.com/3/abc/ You can also check out zope.interface which was used prior to introduction of ABC in python. http://pypi.python.org/pypi/zope.interface https://zopeinterface.readthedocs.io/en/latest/README.html
