Question

2, (10 points) Given the Python class below, pertorm the folloving tasks: a. Name all mutator methods b. Give the output e. Give code to create a sibling class to Rectangle named RightTriangle d. Give code to create a RightTriangle, RT, class Shape: def init_(self, width, height): self.w- width self,h = height def setwidth(self, width): self.w-width def setHeight (self, height): self.h- height class Rectangle (Shape): def name (self): return "rectangle" def area (self): return (self.w self.h) def main): r Rectangle (3, 6) r.setwidth (4) print ('The 'r.name ()+has an area of str(r.area())+ '.' main()

Explanation / Answer

# your code goes here

class Shape:

def __init__(self,width,height):

self.w = width

self.h = height

def setWidth(self,width):

self.w = width

def setHeight(self,height):

self.h = height

class Rectangle(Shape):

def name(self):

return "rectangle"

def area(self):

return (self.w * self.h)

class RightTriangle(Shape):

def name(self):

return "right triangle"

def area(self):

return int(1/2 *self.w * self.h)

def main():

r = Rectangle(3,6)

r.setWidth(4)

print('The '+r.name()+' has an area of '+ str(r.area())+'.')

RT = RightTriangle(3,6)

print('The '+RT.name()+' has an area of '+ str(RT.area())+'.')

main()

1. Mutator Methods: The methods which change the state of variable

So we have setWidth and setHeight as the Mutator Methods

2. Output:

Code for RightTriangle class

class RightTriangle(Shape):

def name(self):

return "right triangle"

def area(self):

return int(1/2 *self.w * self.h)

4. Code for creating a RightTriangle object RT

RT = RightTriangle(3,6)

print('The '+RT.name()+' has an area of '+ str(RT.area())+'.')

//This would print the area and name as:
