Since their inclusion in Python 3.6, f-strings have become the preferred way to format strings with variable values as they are generally more readable as the value substitution is in place and doesn't have to be parsed from the list or arguments to `.format()`. Where it does not impact readability (when the line is <120 characters), swap usage of `.format()` to an f-string. For lines that are not converted, inform the linter to ignore attempts to upgrade those instances to f-strings [0] [0]: https://docs.astral.sh/ruff/rules/f-string/ Signed-off-by: Vincent Fazio <vfazio@xes-inc.com> Link: https://lore.kernel.org/r/20241114145116.2123714-23-vfazio@xes-inc.com Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
