Learn to write cleaner, more modular, and more scaleable code in Python by gaining a master of Object Oriented Programming (OOP). 

You'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 you'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

Learn Object-Oriented Programming in Python

In this lesson, we will implement a class named `Employee` in Python.  

# Implementation of the `Employee` class

Let's implement the `Employee` class illustrated below. We'll start with just adding the properties of the class.

# this code will compile
class Employee:
    # defining the properties and assigning them none
    ID = None
    salary = None
    department = None


With_None

# this code will give a compilation error
class Employee:
    # defining the properties and not assigning them none
    ID
    salary
    department


Without_None

We have defined three properties as class variables `ID`, `salary` and `department`, for the class `Employee`.

> Note that you do not initialize the values of properties, the Python code will **not compile**. Initializing the values of properties inside the class is necessary. 

The code in the second tab will not compile since the properties in the class have not been initialized.  

Learn how to create properties, both in classes and outside of classes, and how to access them.
