Elevate Your Python Projects: Automate Five Key Development Tasks with Pre-Commit Hooks
<p>you’ve spent days perfecting your Python code, meticulously crafting every function and class to create a masterpiece. But just as you’re about to push it to your repository, you realise — a sinking feeling in your stomach — that there might be lurking bugs, style violations, or even security vulnerabilities hiding within your carefully crafted code. What if there was a way to catch these issues before they ever make it to the repository, saving you countless hours of debugging and headaches? Enter the realm of pre-commit hooks — a powerful ally in the battle for clean, error-free code.</p>
<p>In this article, we’ll dive headfirst into the world of pre-commit hooks for Python, exploring the best libraries to automate five parts of your Python development process, from code style to analysing complexity, and from testing to documentation.</p>
<h1>A quick primer in pre-commit hooks</h1>
<p>Pre-commit hooks are small scripts that are run when you commit code to your branch, for example for static type checking (mypy), code style checks (flake8) or automated re-formatting (Black, end-of-file-fixer, pretty-format-json). To use pre-commit hooks, you’ll need the following:</p>
<ul>
<li>Pre-commit needs to be installed (<code>pip install pre-commit</code>).</li>
<li>A <code>.pre-commit-config.yaml</code> file in the top-level dir of your Python project that specifies the hooks that you want to use.</li>
<li>You need to install the pre-commit hooks that you have configured(<code>pre-commit install</code>).</li>
</ul>
