Warnings

# Install pre-commit
os.system('pip install pre-commit')

# Create a configuration file
with open('.pre-commit-config.yaml', 'w') as f:
    f.write('repos:\n  - repo: https://github.com/pre-commit/mirrors-black\n    rev: v22.10.0\n    hooks:\n      - id: black\n')

# Install the git hook scripts
os.system('pre-commit install')
