Gain mastery over object-oriented programming (OOP) to write cleaner, more modular, and more scalable code.

Zero to Hero in Python

This module aims to teach us how to write cleaner, more modular, and more scalable code in Python by giving us an understanding of object-oriented programming (OOP). We'll start with the basics of object-oriented programming and build up to more advanced concepts such as inheritance, information hiding, and polymorphism. Along the way, we'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP.

Object-oriented Programming in Python


## Declaration

In Python, classes are defined as follows:

The `class` keyword tells the compiler that we are creating a custom class, which is followed by the class name and the `:` sign. 

All the properties and methods of the class will be defined within the class scope.

### Naming rules
The following rules must be adhered to when naming classes: 
 1. Must start with a *letter* or *underscore*
 2. Should only be comprised of *numbers*, *letters*, or *underscores*

## Creating a class object
The name of the class, `MyClass`, will be used to instantiate an object of the class in our main program. We can create an object of a class by simply using the name of the class followed by a pair of parenthesis. It looks similar to calling a function, but Python can distinguish between the two and creates a new object of the corresponding class. An example of this is given below:
