3. Write Python code to define the Ellipse class with a reasonable number of properties and methods. For this assignment, we are learning about inheritance. For the first question, I created a class Circle to inherit from the parent class, Ellipse, using pass. For this question, I had to write a working code using class Ellipse, showing some properties and methods. I wanted to make sure I did it correctly and commented correctly. Any help would be appreciated, thanks. ---------------------------------------------------------------------------------------------------------- import math # create parent class - ellipse class Ellipse: # parent class instance attribute def __init__(self, length, width): self.length = length self.width = width # use math.pi for value of pi # calculate and return area of ellipse def area(self): return math.pi * self.length * self.width # calculate and return perimeter of ellipse def perimeter(self): return math.pi * (self.length + self.width) # create child class - circle class Circle(Ellipse): # child class instance attribute def __init__(self, radius): # super function used to inherit from parent class super().__init__(radius, radius) # to get radius def getRadius(self): return self.length def main(): # enter and read length and width of the ellipse length = float(input('Enter the length of ellipse: ')) width = float(input('Enter the width of ellipse: ')) # create an object of the ellipse class e = Ellipse(length, width) # display ellipse length/width/area/perimeter print('Ellipse Length: ', e.length) print('Ellipse Width: ', e.width) print('Ellipse Area: ', e.area()) print('Ellipse Perimeter: ', e.perimeter()) # enter and read radius of the circle radius = float(input('Enter the radius of circle: ')) # create an object of the circle class c = Circle(radius) # display circle radius/area/perimeter print('Circle Radius: ', c.getRadius()) print('Area: ', c.area()) print('Perimeter: ', c.perimeter()) # call main function to start executing program main()
