python-class-and-filename

To maintain consistent import paths in Python, name your main class in PascalCase and place it in a snake_case file named after that class. This ensures a clean import structure and makes modules easier to locate.

The best way to structure a Python module is to define one main class per file using PascalCase for the class name and snake_case for the filename. This approach improves code clarity and simplifies refactoring.

You should use a function module instead of a class when your code does not require state management or object-oriented patterns. This keeps your Python modules lightweight and avoids unnecessary class wrappers.

To refactor Python class naming conventions, rename the class to PascalCase and update the containing module to a matching snake_case filename. This standardizes module structure and resolves import hygiene issues.

Inconsistent Python module naming makes refactoring difficult because it leads to confusing import paths and fragmented code structure. Standardizing class and snake_case filenames resolves this by creating a clear, predictable import hierarchy.

Standardizing Python class filenames works for both existing codebases and new projects. You can apply these conventions during module refactoring to improve import hygiene or use them when adding new classes to ensure consistent structure.
