Inconsistent formatting around power and brackets

[tobiasdiez]

The expression

rho = sqrt(r**2 + a**2 * cos(th)**2)

is reformatted (ruff format) as

rho = sqrt(r**2 + a**2 * cos(th) ** 2)

Note the additional space around ** after the cosine.

Thanks for the report! In general, Ruff's formatter tries to apply the same style to Python code as Black. I checked and Black applies the same style here that we do. The motivation for this formatting is described in Black's documentation here: https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#line-breaks-binary-operators. We've previously made chnages in the opposite direction to what you're asking for here, e.g. #7318, in order to ensure a compatible coding style with Black.

This doesn't mean that we definitely won't change the style of how we format power expressions -- we do deviate from Black in some areas. But deviations generally require very strong motivations and high levels of user demand, as we weigh compatibility with Black quite highly.
