Computer Science:Python programming.

This assignment requires you to create two files; a module defining 4 classes and an executable program that tests the classes. The module file defines a superclass Edifice (supplied below) and 3 subclasses that you must code. Follow instructions closely for full points.

class Edifice:

def __init__(self,storeys,area):

self.__storeys = storeys

self.__area = area

def show_info(self):

print(‘Storeys:’,self.__storeys,’, floor area:’,self.__area)

class Home:

  • inherits from Edifice and adds a numeric attribute for number of bedrooms.
  • overrides the show_info() method by:
    • calling the Edifice class show_info() method to display the storeys and area attributes.
    • printing the purpose of a home and the number of bedrooms.

class Factory:

  • inherits from Edifice and adds a string attribute for the product manufactured by the factory.
  • overrides the show_info() method by:
    • calling the Edifice class show_info() method to display the storeys and area attributes.
    • printing the purpose of a factory and the product it manufactures.

class Commercial:

 

  • inherits from Edifice and adds a string attribute for the usage of the commercial building.
  • overrides the show_info() method by:
    • calling the Edifice class show_info() method to display the storeys and area attributes.
    • printing the purpose of the commercial building and the usage.

In the executable file’s main function:

  • create a Home instance and execute its show_info() method.
  • create a Factory instance that manufactures automobiles and execute its show_info() method.
  • create a Commercial instance to represent an office building and execute its show_info() method.
  • create another Commercial instance to represent a mall and execute its show_info() method.
