Recommended way to implement __eq__ and __hash__

Question

The python documentation mentions that if you override __eq__ and the object is immutable, you should also override __hash__ in order for the class to

Answer 1

Answering my own question. It seems one way of performing this is to define an auxillary __members function and to use that in defining __hash__ and __eq__. This way, there is no duplication:

class MyClass(object):
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def __members(self):
        return (self.a, self.b)

    def __eq__(self, other):
        if type(other) is type(self):
            return self.__members() == other.__members()
        else:
            return False

    def __hash__(self):
        return hash(self.__members())

Answer 2

Is that the equivalent of this one-liner eq?

   def __eq__(self, other):
       return type(other) is type(self) and (self.a == other.a) and (self.b == other.b)
