Worked on the FZJ-IEK3-VSA/FINE repository to overhaul the core library’s documentation, focusing on improving code readability and maintainability. Introduced comprehensive docstrings across key methods and functions, ensuring that the Python codebase adheres to clear documentation standards. Integrated Ruff as a linting tool to enforce docstring consistency, while configuring exclusions for test files to streamline the process. This targeted approach enhanced API clarity and supports smoother onboarding for new developers. The work emphasized code quality and documentation best practices, resulting in a more maintainable library and establishing a foundation for future contributions and collaborative development within the Python ecosystem.
