Summary of Changes

Hello @Wangmerlyn, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a type hinting inaccuracy within the logger utility. The primary change ensures that the _parse_log_level function's default parameter correctly indicates its ability to accept an optional integer value, improving code clarity and type safety. Additionally, minor import reordering was performed for consistency.

Highlights

• Type Hint Correction: Updated the type hint for the default parameter in the _parse_log_level function from int to Optional[int] to correctly reflect that it can accept None.
• Import Reordering: Reordered import statements for Path and Optional in src/keep_gpu/utilities/logger.py for stylistic consistency.

Code Review

This pull request correctly fixes a type hint for the default parameter in the _parse_log_level function, changing it from int to Optional[int]. This change aligns the function signature with its usage, as it can be called with None. The accompanying alphabetical sorting of imports is also a good stylistic improvement. The change is correct and improves the overall quality of the code.
