The python black project.

Hi everyone, Black is project to format Python code. It's more and more used by the python community. That can save time and harmonize the code. For example, simple quote versus double quote, that was not checked by pep8.i It's just an example of what make black With a pre-hook commit hook this will be also avoid to lose time with pep8 errors. Two links to see more: https://github.com/ambv/black https://www.mattlayman.com/blog/2018/python-code-black/ I think it can be very interesting to start to use Black on OpenStack. What do you thinks about that? For example, we can introduce it on some projects, I would volunteer to try on TripleO. My best regards
