🐍 Mastering Python Classes: A Beginner's Guide

In this post, we’ll break down Python classes, explain their key components, and provide examples to get you started.

1. What Is a Class in Python?

A class is a blueprint for creating objects. It defines attributes (**variables**) and methods (**functions**) that objects created from the class will have.

Think of a class like a cookie cutter 🍪—it defines the shape, but each cookie (object) made from it can have different properties.

Here’s how you define a basic class in Python:

Output:

Buddy says Woof! 🐶

2. Breaking Down the Code

1. class Dog: – Defines a new class named Dog.

2. __init__ (Constructor) – This special method runs when an object is created, initializing attributes like name and breed.

3. self – Refers to the instance of the class (like my_dog).

4. Method (bark) – Functions inside a class that define behaviors.

3. Creating Multiple Objects

Each object can have different properties while following the same structure:

4. Class vs. Instance Variables

• Instance variables belong to a specific object self.name).

• Class variables are shared across all instances.

Example:

Changing wheels in Car will affect all instances, but modifying brand only affects that specific object.

5. Encapsulation (Protecting Data)

Encapsulation restricts access to certain attributes to prevent accidental modification:

Here, __balance is private and can't be accessed directly account.__balance would raise an error).

6. Inheritance (Reusing Code)

Inheritance allows one class to derive from another, reusing its methods:

🏆 Conclusion

Python classes make your code organized, efficient, and scalable. By mastering objects, methods, inheritance, and encapsulation, you’ll write cleaner, more professional code!
