Python Functions vs. Classes
Know when to use which one in this quick tutorial.
Everyone starting learning Python will get to this question sooner or later.
What is the best way to structure your code?
Should you use custom functions or classes?
Let’s break down when each one shines.
Functions
We can think of functions as mini-programs that do one specific task. Something like: here are these two numbers; add them and tell me the result.
Functions are Simple and Straightforward. A piece of code to repeat over and over.
When you only need to perform a single action, functions are your best bet. For example, calculating the area of a circle or converting temperatures. Don’t overcomplicate things!
Classes
Now, classes are like blueprints for creating objects. And we know that Python (like some other programming languages) is Object-Oriented, meaning that the object determines what you can or cannot do with it. Objects can have characteristics (attributes) or do something (methods).
- Object: What it is →
Dog - Attributes: How can I describe it →
color,race…
