Grant Opportunity: Python - PSF Grants Program
https://www.python.org/psf/grants/
This grant is funding from the Python Software Foundation for funding specific projects with a clear objective that involves the use and development of Python. The first projects that comes to mind for this one is PyGTK and PyGObject. I'm not sure if those are ran under the GNOME umbrella, but there sure seems to be a lot of applications using it. Maybe any sort of funding from this could go towards a Outreachy intern or the sort.
The Python Software Foundation welcomes grant proposals for projects related to the development of Python, Python-related technology, educational programs and resources. If you have questions about the Grants program, please read the FAQ and direct questions to psf@python.org.
