If you’re a Python developer, you may frequently come across situations where your team members have different coding styles that make the codebase inconsistent. As a result, this leads to bugs, decreases productivity, and makes collaboration difficult.

As someone who strives to maintain code quality, I know how painful this situation can be.

👉 There is fortunately a solution that solves this issue: pre-commit hooks.

Pre-commit hooks are scripts or tools that run before you make a commit to your version control system. They can automatically format your code, run tests, check for linting errors, and much more.

I started using pre-commit hooks in both my personal and professional projects. They have helped me catch and fix potential issues early on, ensuring that my code is always clean and consistent. Plus, they have saved me a lot of time and effort by automating repetitive tasks.

In this practical blog post, we will dive into this topic. We will explore how to set pre-commits, customize them to suit your needs, and integrate them into your development workflow.

If you’re a Python developer looking to enhance your code quality and productivity across your team, this post is for you.

So, without further ado, let’s have a look 🔍

Pre-commit hooks are scripts that run automatically before each commit to check your code for errors. These hooks are language agnostic and help to catch issues before they are committed to the repository, ensuring that only high-quality code is committed.

The following diagram visualizes a git workflow that includes the pre-commit hooks: once you hit the git commit command, these scripts are triggered. And when they’re done executing, a final step verifies that all the checks passed.
