Closes #19350 This fixes a syntax error caused by formatting. However, the new tests reveal that there are some cases where formatting attributes with certain comments behaves strangely, both before and after this PR, so some more polish may be in order. For example, without parentheses around the value, and both before and after this PR, we have: ```python # unformatted variable = ( something # a comment .first_method("some string") ) # formatted variable = something.first_method("some string") # a comment ``` which is probably not where the comment ought to go. |

Ruff Formatter
The Ruff formatter is an extremely fast Python code formatter that ships as part of the ruff
CLI.
Goals
The formatter is designed to be a drop-in replacement for Black, but with an excessive focus on performance and direct integration with Ruff.
Specifically, the formatter is intended to emit near-identical output when run over Black-formatted code. When run over extensive Black-formatted projects like Django and Zulip, > 99.9% of lines are formatted identically. When migrating an existing project from Black to Ruff, you should expect to see a few differences on the margins, but the vast majority of your code should be unchanged.
If you identify deviations in your project, spot-check them against the intentional deviations enumerated below, as well as the unintentional deviations filed in the issue tracker. If you've identified a new deviation, please file an issue.
When run over non-Black-formatted code, the formatter makes some different decisions than Black, and so more deviations should be expected, especially around the treatment of end-of-line comments. For details, see Style Guide.
