Python’s simplicity and versatility make it one of the most popular programming languages today. However, writing clean and maintainable Python code requires adherence to a set of best practices that go beyond simple syntax.

In this article, I’m going to explain to you some key principles and techniques for crafting high-quality Python code that stands the test of time.

1. Follow the PEP 8 Style Guide

PEP 8 is Python’s official style guide and serves as the foundation for writing readable and consistent code. Some key guidelines include:

• Indentation: Use 4 spaces per indentation level.

        pass

Use tools like black or flake8 to automatically format and check your code against PEP 8.
