How do you feel about black code style?

[sgbaird]

Spyder allows for automatic black formatting - and I'm wondering if you're OK with me submitting a pull request that's had this auto-formatting applied to ElM2D.py.

There are some lines of code that opinionated me would disagree with black on, which is line length, e.g. keeping the if verbose: print(... statements on a single line I think looks a bit cleaner when reading through the code when there's lots of them (although many of these are a bit unnecessary at the moment).

Feel free to run it and pull and will see how it looks though, as there are definitely some other lines of code which should be broken up a bit further, and really interested to see what the function you've been working on is!
