Please make sure that the bug is not already fixed either in newer versions or the

current development version. To confirm this, you have three options:



1. Update Black's version if a newer release exists: `pip install -U black`

2. Use the online formatter at <https://black.vercel.app/?version=main>, which will use

   the latest main branch.

3. Or run _Black_ on your machine:

   - create a new virtualenv (make sure it's the same Python version);

   - clone this repository;

   - run `pip install -e .[d,python2]`;

   - run `pip install -r test_requirements.txt`

   - make sure it's sane by running `python -m pytest`; and

   - run `black` like you did last time.
