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: Make Animal the parent. 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: Make Animal the parent. 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. Create a test program that will: 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. (Don't forget this!)

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
Use Python
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:
- Make Animal the parent.
- 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:
- Make Animal the parent.
- 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.
Create a test program that will:
- 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. (Don't forget this!)
