🌟 Summary

Improving code quality by updating pre-commit hooks and scheduling.

📊 Key Changes

• Changed the pre-commit autoupdate schedule from quarterly to monthly.
• Upgraded Python code formatting to apply to version 3.7 and newer (--py37-plus).
• Tweaked Markdown (MD) formatting exclusion pattern.

🎯 Purpose & Impact

• 🔄 More Frequent Updates: Monthly updates to pre-commit hooks will ensure code standards are regularly checked with the latest tools, providing more consistent quality over time.
• 🐍 Python Version Upgrade: The shift to --py37-plus indicates a move towards newer Python features and away from deprecated 3.6 syntax, which can lead to more optimized and future-proof code.
• ✏️ Markdown Formatting: The modification in the MD formatting exclusion pattern might mean increased consistency in documentation with fewer exclusions to formatting rules.

Users can expect better-maintained code with adherence to the latest best practices in code formatting and a gradual phasing out of older Python syntax.
