PyHC: Promoting the Use and Development of Sustainable Open-Source Python Software across the Solar and Space Physics Community

Since its creation in 2018, the Python in Heliophysics Community (PyHC; pyhc.org) has facilitated scientific discovery by promoting the use and development of sustainable open-source Python software across the solar and space physics community; improving communication and collaboration between disciplines, developers, and users; establishing and maintaining development standards; and fostering interoperability and reproducibility. Through these efforts, PyHC has amassed a large swath (> 60 packages) of solar and space physics open-source Python software. This submission will cover a brief background of PyHC, PyHC's best practices and standards for the community’s software, which is crucial in providing sustainable and trustworthy tools for the community to access data, sharing, analysis, etc., as well as show examples of how PyHC enables an open-source Python software ecosystem for Heliophysics research and education via leveraging multiple PyHC packages to solve a science problem.
