black formatter
Domain: CI CD Automation
🎯 Motivation
black is an opinionated code formatter that reformats Python files to a single canonical style. It eliminates style debates in code reviews by making formatting automatic and non-negotiable.
📋 Concrete Example
You run black . and it reformats x=1 to x = 1, wraps long lines, and normalizes quotes. The diff shows only formatting changes, never logic changes.
🔗 Analogy
black is like a uniform policy at a school. Everyone wears the same outfit (style), so nobody argues about fashion and focus stays on learning (logic).
