To structure a Python project with a src layout, you should organize package code under a src/ directory, separate tests, and define configuration files. This approach keeps your codebase understandable and prevents import errors as the project grows.

The best way to write safe SQLite queries in Python is to use parameterized queries and explicit schemas. Safe connection patterns and cautious handling of destructive operations prevent SQL injection and ensure transaction-aware database access.

To refactor Python code without breaking existing APIs, preserve public interfaces and split overly large modules. You should add or update tests before refactoring and document behavior changes clearly to ensure safe evolution of existing code.

To document a bug fix with a regression test in Python, create a minimal reproduction, write a failing test, and fix the behavior. You should then produce clear commit messages and optional changelog entries to reduce future regressions.

Python code refactoring requires PEP 8 style consistency and docstrings for public APIs. Promoting code clarity practices, including signal-rich comments explaining the “why,” ensures the refactored modules remain maintainable and understandable.

You should split large Python modules during refactoring when module boundaries become unclear or files grow overly complex. This improves code structure, preserves existing APIs, and maintains a manageable project scaffold as the codebase evolves.
