## Code


We start to fill the `Cat` class:
  - An attribute `name` with the predefined value `'Kitty'`;
  - A method `say_meow()`. 
 
We create an object `cat` and call the `say_meow()` method.

class Cat:
  # An attribute
  name = 'Kitty'
  # A method
  def say_meow(self):
    print('Meow')

# Instantiating an object
cat = Cat()
cat.say_meow()

## Note

 - Each method obligatory contains `self` - a reference to the current object;
 - To call the method of the object, write `Object.Method()`.

The object-oriented paradigm allows developers to create and structure programs using objects with predefined behavior. This is a widely used style of software organization that is easy for the development team to understand. Like most other programming languages, Python supports and implements this paradigm.

The first step is to understand the key statements. Classes, objects, attributes, methods...

Encapsulation provides access to the methods and attributes of the class.

Inheritance's main idea is to use already defined classes and produce new ones by improving and extending some other classes.

This OOP principle allows the user to change the parent class functionality and adapt it to the children's class.
