Python Classes

Python Classes

Python has classes like other object-oriented languages. Python, as a result, can embrace the object-oriented architecture. Today, we go into what classes are and the syntax of Python classes.



Classes are templates for objects in object-oriented languages. Objects are just a concept used in programming to build better systems. Here’s the idea.

If I wanted to build a car; the car has an engine, turning system, and lights. In this case, I would create the car by composing the car out of objects of the class car, engine, turning system, and lights.  Classes allow you to create objects based on that template. This is the idea that drives object oriented programming. So, how does that idea get implemented in python? Let’s look.


Python Class Syntax

Classes in Python implement the same concept. However just use Python syntax, one thing to note is that because Python’s functions have unique properties, you can use that in class creation. Here’s an example of creating a car class in Python that takes a turning system, lights, and engine.

In this example, you can see some of those function properties in use. Now, the most important function in your Python class is the __init__ function. This class method allows you to create classes that take parameters. Note that every method (a function within a class) must start with the parameter self in Python in order to be considered a part of that instance. Furthermore, there is the super keyword that allows you to use code inherited from another class. Inheritance is a core concept of object-oriented programming but should be used sparingly if possible.


I hope this post helped you learn the basic idea of class creation in the Python language. However, I’m sure there are more versatile ways to create classes, such as static classes. Stay tuned as we go into conditional statements in Python! Soon, we’ll start building a basic command line tool using Python.
