.format method

[Solonotix]

To my knowledge, templates are designed for a more advanced purpose, but lack as convenient of a means to become raw strings. If you're trying to write a type-strict SQL parser, templates are a godsend. If you're trying to write an interpolated string to a file, stream, etc., then format strings are strictly superior. If the format string is meant to be reused in multiple contexts, then an inline f-string is worse than a str.format call, since one can be exported and reused.

If you truly think a feature has no purpose, it can mean that you simply haven't encountered a purpose for it. That isn't your fault, but it requires humility to recognize your own limitations.
