Worked on enhancing the pyOpenSci/python-package-guide repository by implementing localization features to expand international accessibility. Focused on adding missing .po files for Japanese and Portuguese, and updated Spanish translations for key documentation pages such as add license, README, and CLI reference. Utilized Python and translation tools to streamline the workflow, collaborating with teammates and integrating pre-commit CI checks to maintain formatting and translation quality. These efforts improved the guide’s usability for non-English speakers, particularly Spanish-speaking users, and aligned the documentation with internationalization best practices, ultimately broadening the global reach and inclusivity of the Python package guide project.
