Worked on TheAlgorithms/Python repository to improve the accuracy and reliability of documentation and testing for Fibonacci functions. Addressed a bug by correcting doctest references in function docstrings, ensuring that documentation examples now accurately reflect actual function usage and outputs. This change reduced the risk of confusion for users and stabilized the automated test suite. Leveraged Python for both algorithm development and unit testing, while utilizing pre-commit hooks and continuous integration workflows to enforce code formatting and correctness. The work focused on maintaining high code quality standards and enhancing the clarity of documentation, contributing to a more robust codebase.
