In this Python tutorial, we'll be learning how to use Ruff, a super-fast Python linter and formatter written in Rust. We'll cover how to install Ruff, how to use Ruff from the command line to check and fix your code, and how to configure Ruff both for individual projects and globally. You'll also learn how to integrate Ruff with VSCode to get real-time feedback as you code. Ruff is growing rapidly in popularity because it consolidates multiple Python tools like Flake8, Black, isort, and others into a single, faster solution that significantly improves code quality. By the end, you'll be equipped to use Ruff in your own Python projects. Let's get started...
