I'm a PhD student who was almost entirely focused on lab work this semester, and with labs closed for the foreseeable future due to coronavirus, I'm finding myself with a bunch of free time. I only have one class and I considered studying for my doctoral exams a little early, but don't feel like I'm in the right spot mentally right now to do that. With that in mind, I'm thinking of learning Python or some sort of other programming language. I'm aware of all the resources out there to start learning, but does anyone have suggestions on how to find a good dataset to start working with? I'm in the water resources sector. Anything related to water, sanitation, agriculture, climate change, etc. would be interesting. Other suggestions for how researchers like me can stay productive and learn skills would be great too, thanks!
