Compiling Black with mypyc (via) Richard Si is a Black contributor who recently obtained a 2x performance boost by compiling Black using the mypyc tool from the mypy project, which uses Python type annotations to generate a compiled C version of the Python logic.

Black 22.1.0 (via) Black, the uncompromising code formatter for Python, has had its first stable non-beta release after almost four years of releases. I adopted Black a few years ago for all of my projects and I wouldn’t release Python code without it now—the productivity boost I get from not spending even a second thinking about code formatting and indentation is huge.
I know Django has been holding off on adopting it until a stable release was announced, so hopefully that will happen soon. # 30th January 2022, 1:23 am

Black Onlline Demo (via) Black is “the uncompromising Python code formatter” by Łukasz Langa—it reformats Python code to a very carefully thought out styleguide, and provides almost no options for how code should be formatted. It’s reminiscent of gofmt. José Padilla built a handy online tool for trying it out in your browser. # 25th April 2018, 5:17 am
