Current style <current_style> Future style <future_style>
Black is a PEP 8 compliant opinionated formatter with its own style.
It should be noted that while keeping the style unchanged throughout releases is a goal, the Black code style isn't set in stone. Sometimes it's modified in response to user feedback or even changes to the Python language!
Documentation for both the current and future styles can be found:
