Python Style Guide - PEP 8 and Code Formatting


Consistent and readable code is essential for collaboration and maintainability in Python projects. Python Enhancement Proposal 8 (PEP 8) is the official style guide for Python code, providing recommendations for formatting, naming conventions, and more. In this guide, we'll explore PEP 8 and code formatting best practices.


Before you begin, make sure you have the following prerequisites in place:

  • Python Installed: You should have Python installed on your local environment.
  • Basic Python Knowledge: Understanding Python fundamentals is essential for writing and formatting code according to PEP 8.
  • Text Editor or IDE: You can use any code editor or integrated development environment (IDE) for writing and formatting Python code. Many code editors have PEP 8 linting and formatting tools built in.

PEP 8 Basics

PEP 8 covers various aspects of code formatting, including:

  • Indentation and spacing.
  • Naming conventions for variables, functions, classes, and modules.
  • Comments and docstrings.
  • Imports and whitespace in code.

Sample Python Code Following PEP 8

Here's an example of Python code that follows PEP 8 recommendations for indentation, naming, and spacing:

def calculate_total_cost(item_price, quantity):
Calculate the total cost for a given item and quantity.

item_price (float): The price of the item.
quantity (int): The quantity of items.

float: The total cost.
total_cost = item_price * quantity
return total_cost


Adhering to PEP 8 and following code formatting best practices is a fundamental skill for Python developers. Properly formatted code improves code readability and maintainability. This guide has introduced you to the basics of PEP 8 and code formatting recommendations. As you continue to work with Python, you'll find that applying these guidelines makes your code more consistent and easier to collaborate on.
