Probably.

This is a particularly simple example, with only getters. How would you write it
by overriding __get__?


class Circle(object):
    def __init__(self, centre, radius):
        self.centre = centre
        self.radius = radius

    @property
    def diameter(self):
        return 2*self.radius

    @property
    def area(self):
        return pi*self.radius**2

    @property
    def circumference(self):
        return pi*self.diameter
