Code style preferences

[Erick G. Islas-Osuna]

Hey everyone!

I'm looking at the code and I saw that there are some inconsistencies between code formatting, mainly in the usage of quotes (" on some strings and ' in other cases).
So what do you think about establishing some preferences on code style? I mean, we already have flake8 to check whether the code follows some PEP8 recommendations, but I want to be sure before adding extra elements or something that could break the current approach?

I know that we have this section and that we are following this guide and PEP8, so I just want to be sure that we are in the same channel.

Also if we don't want to start adding a lot of manual/custom rules, we can work directly with an unopinionated framework like black, which usually follows everything in the PEP8 (except for the double quotes).

Thanks in advance!
