Thank you for the documentation ! I think we need a detail.rst saying f-string performance at a lot better with a link to this tweet from a python core dev : https://twitter.com/raymondh/status/1205969258800275456. Also added more technical f-string with float formatting because often it's not known that this kind of thing can be done with fstring too
