at FOSS4G 2019 we delivered a 'Doing Geospatial in Python' workshop which was well attended. The workshop is on GitHub and folks can start at https://geopython.github.io/geopython-workshop/ and go from there (you need Docker and docker-compose). Any feedback, suggestions, improvements are appreciated!
In addition, we have a living Geopython presentation at http://geopython.github.io/presentation/ which can be used when describing some projects from the Geopython community (updates welcome).
I have a junior python developer friend that wants to start contributing with open source on hacktober (this month). She's good and she asked me if I know of any python project where she can ask and start. Is anyone interested in mentoring her and give her some tasks to do? No geo background.
