    Functions can return instances. For example, find_center takes a Rectangle as an argument and returns a Point that contains the coordinates of the center of the Rectangle:

    def find_center(rect):
        p = Point()
        p.x = rect.corner.x + rect.width/2.0
        p.y = rect.corner.y + rect.height/2.0
        return p
    

    Here is an example that passes box as an argument and assigns the resulting Point to center:

    >>> center = find_center(box)
    >>> print_point(center)
    (50.0, 100.0)
