Worked on enhancing the sympy/sympy repository by adding detailed docstrings to the Rational class’s numerator and denominator properties, addressing a key documentation issue and improving API clarity for developers. Focused on aligning new documentation with existing project standards, the work promoted consistency and easier onboarding for contributors. Utilized Python and object-oriented programming principles, with an emphasis on code documentation practices and structured commit messaging. The contribution did not involve bug fixes but centered on improving developer usability and maintaining high documentation standards, reflecting a methodical approach to code quality and collaborative development within the open-source Python mathematics library.
