Εργασία 7.1

We have learned how to create classes and objects.

Create a new program, test it and upload it using your name and followed by AS7.1 in the programs file name. As an example a programs filename could be Name_Surname_AS7.1.py

For your effort you will be graded and you will have another try if you want to get a better grade. Passing grade is 60%

The program should start with three class definitions, then code that will create instances of each class.

Write code that defines a class named Animal:

•         Add an attribute for the animal name.
  
•         Add an eat() method for Animal that prints ``Munch munch.''
  
•         A make_noise() method for Animal that prints ``Grrr says [animal name].''
  
•         Add a constructor for the Animal class that prints ``An animal has been born.''
  

A class named Cat:    

•         A make_noise() method for Cat that prints ``Meow says [animal name].''
  
•         A constructor for Cat that prints ``A cat has been born.''
  
•         Modify the constructor so it calls the parent constructor as well.
  

A class named Dog:

•         A make_noise() method for Dog that prints ``Bark says [animal name].''
  
•         A constructor for Dog that prints ``A dog has been born.''
  
•         Modify the constructor so it calls the parent constructor as well.
  

A main program with:

•         Code that creates a cat, two dogs, and an animal.
  
•         Sets the name for each animal.
  
•         Code that calls eat() and make_noise() for each animal.
