PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Use array for target-version Ruff expects target-version to be a TOML array of strings rather than a single string. Converting to an array ensures future support for multiple versions and correct parsing. pyproject.toml [154] -target-version = "py39" +target-version = ["py39"] Suggestion importance[1-10]: 8 __ Why: The target-version setting in Ruff expects a TOML array of strings, so using ["py39"] ensures correct parsing and allows future multiple versions.
