+rules, omitting any stylistic rules that overlap with the use of a formatter,

+[`B012`](https://docs.astral.sh/ruff/rules/jump-statement-in-finally/), which
+corresponds to a `SyntaxWarning`, and
+[`PYI057`](https://docs.astral.sh/ruff/rules/byte-string-usage/), which flags
+usage of some long-deprecated APIs in the standard library.
 
 If you're just getting started with Ruff, **the default rule set is a great place to start**: it
 catches a wide variety of common errors (like unused imports) with zero configuration.
