As software systems grow in complexity, adhering to well-established design principles becomes crucial for maintaining code quality, extensibility, and maintainability.

In the world of Python, encapsulation and principles like SOLID, DRY, and KISS play a vital role in writing clean, readable, and scalable code. In this article, we’ll explore these concepts and provide practical examples to help you level up your Python programming skills.

Encapsulation: Hiding Implementation Details

Encapsulation is a fundamental concept in object-oriented programming (OOP) that involves bundling data and methods together within a class, and controlling access to the class members.

By encapsulating data and methods, you can hide the implementation details from the outside world, promoting code modularity and reducing dependencies. In Python, you can achieve encapsulation by using naming conventions and access modifiers. Here’s an example:

class BankAccount:
    def __init__(self, balance):
        self._balance = balance  # Protected attribute

    def deposit(self, amount):
        self._balance += amount…
