Stop Pushing Broken Code: The Simple Pre-Commit Setup Every Python Developer Needs

Discover how Pre-Commit can automatically format, lint, and secure your Python code. Learn to set it up, prevent errors, and keep your projects clean and consistent.

Good code isn’t just about making something that runs—it’s about keeping it clean and easy to work with as your project gets bigger. That’s where pre-commit comes in. Think of it like a security guard for your code.

Before any changes get committed, it checks everything to make sure you’re not adding sloppy formatting, forgotten print statements, or anything that breaks your team’s standards.

With pre-commit, you can automatically run tools like Black, Flake8, or isort before your code even hits the repository. It keeps your project clean without you having to remember to do it yourself.

I’ll be honest—I used to forget to lint or format my code all the time. I’d push changes and later realize half my files didn’t match our style rules. Once I started using pre-commit, that problem disappeared.

It quietly took care of everything each time I ran git commit. It’s one of those small tools that make a big difference, especially when you’re working with a team or managing a growing codebase.
