About Black
Black formats Python code and doesn't ask questions. No configuration options, no style debates—feed it code, get back consistently formatted output. The format is opinionated, and that's the point.
Integration with editors reformats on save. CI checks ensure commits are formatted. Teams stop arguing about style because Black decides for everyone.
Python teams adopt Black to end formatting discussions forever. The loss of control is a feature, not a bug.
