So the root of this argument is that Black produces code that isn’t always in compliance with PEP 8. I say this is fine – if you use Black you don’t need PEP 8 to tell you how to format your code. (PEP 8 is still useful for other things like naming things.)
Black optimizes for a different goal than PEP 8; PEP 8 optimizes for readability while Black sometimes compromises readability in order to satisfy other goals such as minimizing lines changed as code evolves.
I don’t want to compromise PEP 8 though.
