Question

Python: inheritance. Adding delta_x and delta_y to the 'Shape' class. Note that all other classes inherit from the shape class in this problem. It is the sixth function down. Instructions are on the right side of the screen. My code doesn't work so feel help please.

Answer 1

This code would work. Read and understand it it's pretty simple.

class Shape(object):

def __init__(self, x, y):

self.x = x

self.y = y

class Square(Shape):

def __init__(self, side=1, x=0, y=0):

super(Square,self).__init__(x, y)

self.side = side

class Circle(Shape):

def __init__(self, rad=1, x=0, y=0):

super(Circle,self).__init__(x, y)

self.radius = rad

Now defining the method : as delta

def delta(self, delta_x, delta_y):

self.x += delta_x

self.y += delta_y

Adding this to Shape class:

@add_method(Shape)

def delta(self, delta_x, delta_y):

self.x += delta_x

self.y += delta_y
