Suhaan worked on enhancing the robustness of input validation in the Annotator component of the malariagen/malariagen-data-python repository. Focusing on Python programming and defensive error handling, Suhaan replaced bare assert statements with ValueError exceptions, ensuring that error messages are clearer when reference alleles do not match or when variant coordinates are out of bounds. This approach improved data validation and made debugging more efficient for users of the pipeline. The work demonstrated a solid understanding of Python exception handling and contributed to higher data quality, though it was limited in scope to a single bug fix during the reported period.
