Code Review

This pull request applies ruff formatting to Python code examples across various documentation files, improving code style consistency. The changes are mostly correct and enhance readability. However, I found a critical issue in one of the code examples which contains a syntax error that was present before and was not fixed by the formatting changes. It's important for documentation examples to be syntactically correct.

Code Review

This pull request applies ruff formatting to Python examples in the documentation, which improves code consistency and readability. I've also noted a couple of instances where this formatting pass corrected syntax errors in the code examples, which is a great improvement for the documentation's quality. The changes look good, and I have no further suggestions.

How were you applying the formatting?

We could use https://github.com/adamchainz/blacken-docs to keep the docs formatted this way? Ruff uses the Black ruleset so the formatted code would look the same.

I applied it manually after searching for Python code blocks 😅 that's why I only updated up to features directory

Do you plan to make more changes? Or is it safe to start reviewing?

No, I don't plan to update all examples in this PR
