Practical Python: Class vs Instance Variables

Practical Python: Class vs Instance Variables

In this article, I will focus on class and instance variables. I assume you have a basic knowledge about classes in Python. If not, you can still understand what class and instance variables are but the syntax might look a little overwhelming.

Class is the most fundamental piece of Python because it serves as the essence of object oriented programming.

Everything in Python is an object such as integers, lists, dictionaries, functions and so on. Every object has a type and the object types are created using classes.

Instance is an object that belongs to a class. For instance, list is a class in Python. When we create a list, we have an instance of the list class.

In this article, I will focus on class and instance variables. I assume you have a basic knowledge about classes in Python. If not, you can still understand what class and instance variables are but the syntax might look a little overwhelming.

I have also written an introductory article about Python classes if you’d like to go over the basics.

Let’s start on class and instance variables.

Class variables are declared inside a class but outside of any function. Instance variables are declared inside the constructor which is the initmethod.
