The reason I like black is the most opinonated folks have WEIRD opinions.

You see that here.

Things like a = [ 1, 2, 3 ] when 90% of the world is a = [1, 2, 3]

These folks will spend hours / days try to force weird approaches.

Sometimes they are obviously wrong. But it's annoying to have to fight over it. Something like black saves you the hassle and the WEIRD local coding rules someone comes up with if you are on a project with them.
