Need assistance with a Python program using classes. Several type of shapes will need to be defined: circle, rectangle, and right triangle. These shapes translate directly to classes. Each shape has its own data, a draw method and a get area method. Once the classes have been written, a program will need to be written that will randomly create 15 shapes and have the shapes draw themselves. Assignment instructions attached with a sample run. Please also include comments explaining what everything does.

This assignment will give you practice on writing classes and understanding inheritance. You will define several type of shapes: circle, rectangle, and right triangle. These shapes translates directly to classes. Each shape has its own data, a draw method and a get area method. Once you have written the classes, you will write a program that will randomly create 15 shapes and have the shapes draw themselves. The screen shown below is the result of a sample run.

Shape

has a class variable turtle, initialized to a Turtle object.

Circle

inherits Shape

has a center point, a tuple of x and y

has a radius

has a draw method

has a get_area method

Rectangle

inherits Shape

has an upper_left point

has a lower_right point

has draw method

has get_area method

RightTriangle

inherits Shape

has two points A and B.

has draw method

has get_area method

main function

Generates 15 random shapes.

Draw them

Print their total area

If you are not sure how to start, theres a partial solution on the back you can study. If possible, start from scratch on your own. Heres the link to different operations you can perform with turtle graphics: https://docs.python.org/3.3/library/turtle.html?highlight=turtle

from turtle import Turtle

class Shape():

turtle = Turtle()

class Circle(Shape):

def __init__(self, center, radius): self.center = center self.radius = radius

def get_area(self): return 3.14* self.radius*self.radius

def draw(self): Shape.turtle.penup() Shape.turtle.setposition(self.center[0], self.center[1] - self.radius) Shape.turtle.pendown() Shape.turtle.circle(self.radius) Shape.turtle.penup()

def random_shapes(count):

def random_point(): return (random.randint(-200,200), random.randint(-200,200))

shapes = []

for i in range(1, count+1): shape_type = random.randint(1, 3) if shape_type == 1: shapes+=[Circle(random_point(), random.randint(1,200))] elif shape_type == 2: shapes+=[Rectangle(random_point(), random_point())] else: shapes+=[RightTriangle(random_point(), random_point())]

return shapes

def main():

shapes = random_shapes(15) total_area = 0 for s in shapes: s.draw() total_area += s.get_area()

input("Hit key to end.") print("total area = ", total_area) input("Good bye!")

main()
