Setting up Pre-commit Hooks

What pre-commit does

pre-commit runs checks before a commit is created.

This helps:

• keep formatting consistent
• avoid committing broken code

Example .pre-commit-config.yaml

yaml

repos:
  - repo: https://github.com/psf/black
    rev: 24.10.0
    hooks:
      - id: black
 
  - repo: https://github.com/pycqa/flake8
    rev: 7.1.1
    hooks:
      - id: flake8

Install and run

bash

pre-commit install
pre-commit run --all-files

Tip

Still keep CI checks—hooks are helpful but not a replacement.
