In a similar vein, if there are no local teams near you, getting some sort of microcontroller that runs micropython could be fun too. I’m a big fan of microbit for younger kids, lots of options for lights and sounds, with a few pins for adding sensors/buttons etc.
Thanks for the clarification! Yeah I think you’re right that running python on a github page isn’t possible (at least not straightorward). Replit might be closer to what you’re looking for in that regard. I love it because it handles setting up your programming environment for you and lets you dive right into what you actually want to do (write and run code). Sharing the link to your project lets anyone open it up and run it in their browser!
