Classes Representing Circles Here is a class that represents a circle on the Cartesian plane in 2D: [] import math class Circle(object): _init__(self, x, y, r): "Initializes a circle with center x, y and radius r." self.x = x self.y = y self.r = r @property def area(self): " "Returns the area of the circle. This is defines as a property, so you can call it on a circle c by doing c.area rather than c.area(). return math.pi * self.r * self.r def contains (self, x, y): """Returns true/false according to whether the circle contains the (x, y) point or not." return (x - self.x) ** 2 + (y - self.y) ** 2
