Black formatted 15 files

[Sayam753]

Black formatted last 15 files listed in #4109. This is fun to do. I think in PyMC4, we do have tests for formatting as well.

Thanks @Sayam753 !

This is interesting - once you apply black to

                raise ParametrizationError('Discrete variables are not supported by VI: {}'
                                           .format(var))

then pyupgrade can change it to

                  raise ParametrizationError(
                      f"Discrete variables are not supported by VI: {var}"
                 )

Can you either run pyupgrade on pymc3/variational/opvi.py or install pre-commit and then run

pre-commit run pyupgrade --all

?

This is indeed interesting. I did nothing apart from running black and then why did pyupgrade fail?

Took a while to compare all the lines but 👍

because, once black splits the error message for ParametrizationError so .format is on the same line as a string, then pyupgrade realises it can upgrade it to be an f-string

Wow. pyupgrade is so powerful. Now I am curious to add pyupgrade to VSCode as an auto formatter.
