Black is an amazing tool for auto–formatting Python code in a style that I prefer. I use it in all my projects.
It has one configuration option — to change its default line–length of 88 chars to, say, 79, like PEP8 recommends.
That is exactly what white does. It invokes $ black --line-length 79 on your behalf.
$ white myapp.py
reformatted myapp.py
$ pipenv install white
