O pedaço de código abaixo está me dando um erro por algum motivo, alguém pode me dizer qual seria o problema ..

Basicamente, eu crio 2 classes Point & Circle .. O círculo está tentando herdar a classe Point.

Code:


class Point():

    x = 0.0
    y = 0.0

    def __init__(self, x, y):
        self.x = x
        self.y = y
        print("Point constructor")

    def ToString(self):
        return "{X:" + str(self.x) + ",Y:" + str(self.y) + "}"

class Circle(Point):
    radius = 0.0

    def __init__(self, x, y, radius):
        super(Point,self).__init__(x,y)
        self.radius = radius
        print("Circle constructor")

    def ToString(self):
        return super().ToString() + \
               ",{RADIUS=" + str(self.radius) + "}"


if __name__=='__main__':
        newpoint = Point(10,20)
        newcircle = Circle(10,20,0)

Erro:

C:\Python27>python Point.py

    newcircle = Circle(10,20,0)
