Black

Sometimes creativity can be a wonderful thing. Sometimes it's just a pain. I like to solve problems creatively, but I want my Python format to be as consistent as possible. No one is impressed by the use of "interesting" indented code.

But worse than an inconsistent format is a code review that does nothing but check the format. This is annoying for censors and even more annoying for those being examined. It can also be infuriating when your linter tells you that the code is indented incorrectly but does not indicate the correct amount of indentation.

With Black, it won't tell you what to do, it's a good, hard-working robot: it will fix the code for you.

To understand how it works, feel free to write something very inconsistent, such as:

Def add (a, b): return a+bdef mult (a, b): return\ a * b

Did Black complain? No, it fixed it for you!

$black math reformatted mathAll done! ✨? ✨ 1 file reformatted.$ cat math def add (a, b): return a + bdef mult (a, b): return a * b

Black does provide the option to report errors rather than fix them, and even to output diff editing styles. These options are useful in continuous integration (CI) systems to force Black to run locally. In addition, if the diff output is recorded in the CI output, you can paste it directly into the patch, so that in rare cases you need to repair the output, but you cannot install Black locally.
