Google Summer of Code is a mentorship program for new contributors to open source.  If we provide volunteer mentorship and project ideas, Google will pay selected new contributors to work on an open source project.  You can read more about the program and how it works here: https://summerofcode.withgoogle.com/ 

Python's been taking part for a number of years, and we're applying to do it again this year!  We serve as an "umbrella org" to make it easier for smaller python-based open source projects to take part in the program.  We've got some groups working with us who've been doing this for years, but we're always looking for new projects and new mentors.  If you've got a python-based open source project and wouldn't mind mentoring a new contributor to work on that feature you never quite had time for, we want to hear from you!
