Creating a pre commit rules environment

Got it 👍 Here’s the same setup written in plain text only (no code block formatting), so you can copy it all at once:

Step 1: Install pre-commit

Run in terminal:

pip install pre-commit

Step 2: Create a file named .pre-commit-config.yaml in your project root and put this inside:

repos:

• repo: https://github.com/psf/black
• rev: 24.3.0
• hooks:
• id: black
• 
  
• 
  
• repo: https://github.com/pycqa/isort
• rev: 5.13.2
• hooks:
• id: isort
• 
  
• 
  
• repo: https://github.com/pycqa/flake8
• rev: 6.1.0
• hooks:
• id: flake8
• 
  
• 
  
• repo: https://github.com/pre-commit/mirrors-mypy
• rev: v1.10.0
• hooks:
• id: mypy
• 
  
• 
  
• repo: https://github.com/PyCQA/bandit
• rev: 1.7.9
• hooks:
• id: bandit
• 
  
• 
  

Step 3: Install the hooks

Run:

pre-commit install

Step 4: Run hooks on all files (first time setup)

Run:

pre-commit run –all-files

Now, every time you do git commit, the following will run automatically:

• Black → formats your code
• isort → organizes imports
• Flake8 → checks style issues
• Mypy → checks type hints
• Bandit → scans for security issues
