Having a choice on when to use the existing string formatting methods is a feature. I tend to use ‘%’ a lot for it’s compactness and f-strings most more rarely (admittedly there doesn’t seem to be much reason to use .format these days). In general I don’t understand the need to hard-standardize code. Making subtle decisions depending on context is an important part of programming, please let humans decide and don’t use these types of tools in commit hooks...

  Which is usually an excuse to enforce the personal preferences of some. Programming is not an activity performed by robots (yet).

One case where .format comes in handy: your_dict = { "some": "awesome", "from": "out of", "dictionary": "mapping", } "insert {some} values {from} a {dictionary}".format(**your_dict)

  That is a very neat trick indeed, I'll have to remember this one!

  This can also be achieved using '%': your_dict = { "some": "awesome", "from": "out of", "dictionary": "mapping", } "insert %(some)s values %(from)s a %(dictionary)s" % your_dict WRT .format, '%' is safer to use with untrusted (well, semi-trusted) format strings, whereas .format can lead to code injection (in more insidious ways than with f-strings).

  You'd be better off using "...".format_map(your_dict). This case is exactly why it exists.
