Autoformatting with black?

[consideRatio]

Would a black autoformatting PR be acceptable? I've done it in a few repos at this point, some parts typically gets a bit uglier, a few gets better, but the key feature is a very consistent formatting. There are not many, but a few tricks to influence formatting to look better when black sometimes makes it look worse.

• Influence formatting
  • For example, you can force a function call with arguments to format the arguments over multiple lines by adding a trailing comma, or make it shrink to a single line by removing the trailing comma if it can fit in a single line.
• Adjust to formatting
  If you before had a list of args to call some CLI in an array, and some elements of the list were associated like ["--version", "1.2.3"], then you can avoid having them break into two lines in a larger list by adjusting to a single string flag like this: ["--version=1.2.3"].

---

To conclude, I'd appreciate going for black autoformatting in this repo, as all repo's I work really. I appreciate the forced consistency no matter who makes a PR, and the reduced amounts of changes in PRs after its been applied systematically.

Would it be okay if I applied black autoformatting to this repo, and then also did my best to make it look good?

black should be fine.
