Beside the benefit that black removes any discussion regarding formatting, my favourite benefit otherwise is the speed-up it yields by having it run everytime I save a file. I don't have to care about line lengths or single/double quotes or stuff like that anymore, since black will fix it for me anyway. And if black fails to trigger, it means there is something wrong with my code somewhere.

This is what I've stuffed in my VS code settings:

    "python.formatting.provider": "black",
    "editor.formatOnSave": true,
