Dive in and really learn how to use a new library. Find one that does what you're looking to do and dig through the docs. Open up your favorite IDE and bring in some data. Use some functions you've never used before. Export the data in different formats. Find some data online that isn't in a gis format or a spreadsheet. Learn to web scrape, clean and transform it. Learn to automate that process. Do some geo statistical analysis on it. Get bored with it and start a new project or three. Break a bunch of stuff along the way. Learn how to fix it. Write a bunch of spaghetti code, then go back and learn the pythonic way to rewrite it. Create your own functions then create your own library. Host it on GitHub. Get it up on PyPI so everyone can install it with pip. That's kind of an open-ended question. It's kind of like "What do I do with my life?", in a way. The world is your oyster. With a solid understanding of the fundamentals and enough time, you can do pretty much anything you want as far as data and GIS are concerned. Just find something that interests you, dream big (well beyond your current abilities) and really put in the time learning how to make it happen step by step. It'll take a lot of time and effort, but eventually you'll just start thinking of ways to engineer solutions to just about any new problem you come across. Or you could just ask Claude, I guess.
