> printf-style formatting ("foo %s" % "bar") feels the most ready to be retired (except insofar as it probably never will, because it's a nice shortcut).

It’s also the only one which is anything near safe for being user provided.

I don’t think I’ve ever used % formatting in Python - what makes it safer than `format`?

[masklinn]

`str.format` allows the format string to navigate through indexes, entries, and attributes. If the result of the formatting is echoed back and any non-trivial object it passed in, it allows for all sorts of introspection.

printf-style... does not support any of that. It can only format the objects passed in.

Very good point. While I think we could do away with the syntactic shorthand, definitely would want to keep some function/method around with the capabilities.
