Thanks for helping switch us over to using f-strings!

These were added to python 3.6 now that we've established our python minimum version at 3.6 we can migrate over to using them. To my knowledge this is the current python best practice for string formatting and I think it's a nice improvement overall.

Also looks good to me. Merging once CI passes.

I corrected the one line that failed the formatting check. It should pass the formatter now.
