Worked on the easybuilders/easybuild-easyblocks repository to improve the reliability of build system checks by updating the Miniconda Sanity Check process. Addressed a bug in Python code by removing the deprecated 2to3 executable from the list of expected Miniconda3 binaries, ensuring that sanity checks accurately reflect the current state of Miniconda distributions. This targeted update to anaconda.py reduced false positives in continuous integration workflows and enhanced build reproducibility for downstream users. Demonstrated skills in Python, build system maintenance, and package management, with a focus on precise, commit-based changes that align repository logic with evolving external dependencies.
