Create a class Circle

class Circle(object):

# Constructor
def __init__(self, radius=3, color='blue'):
    self.radius = radius
    self.color = color 

# Method
def add_radius(self, r):
    self.radius = self.radius + r
    return(self.radius)

# Method
def drawCircle(self):
    plt.gca().add_patch(plt.Circle((0, 0), radius=self.radius, fc=self.color))
    plt.axis('scaled')
    plt.show()  

RedCircle = Circle(2, 'red')

#print(RedCircle.drawCircle())

class Rectangle(object):

# Constructor
def __init__(self, width=2, height=3, color='r'):
    self.height = height 
    self.width = width
    self.color = color

# Method
def drawRectangle(self):
    plt.gca().add_patch(plt.Rectangle((0, 0), self.width, self.height ,fc=self.color))
    plt.axis('scaled')
    plt.show()

SkinnyBlueRectangle = Rectangle(5, 3, 'red') print(SkinnyBlueRectangle.height)
print(SkinnyBlueRectangle.width) print(SkinnyBlueRectangle.color)

SkinnyBlueRectangle.drawRectangle()
