I’ve been largely avoiding Black for years, purely because I’m obsessive about coding style and I love how clean Python looks with single quotes (I understand why they made the choice to enforce one style, but I’ve discovered I can be very stubborn!). I would always use linters to check for PEP8 violations, but I’d then fix the style myself.

Unironically the fact that the Ruff autoformatter allows single quotes has made the difference in convincing me to adopt it (although it also helps that Ruff is already my preferred linter!).
