Improve documentation for Python modules #2
Description
Several Python modules lack sufficient in-code documentation. Improve the docstrings and comments to help future contributors understand the purpose and usage of each module, class, and function.
Tasks:
- Review all .py files for missing or unclear docstrings.
- Add or update docstrings for modules, classes, and functions.
- Ensure documentation follows standard style (e.g., Google, NumPy, or reStructuredText).
Acceptance Criteria:
- All major public functions and classes are documented.
- Docstring format is consistent across the codebase.
