Hey, I'm not, the code is sent to the server for execution.
I'm afraid can't help with the libs then ;)
I'd like to have more functionality in-browser, though, like an LSP running as a worker in the background. Do you have any materials that I could read about it or something like that?
As for the questions – I haven't thought much about that, but maybe it would be nice to have. Do you have some ideas on what that simpler than Python could should be? Like e.g. Scratch, or something else?
Replit is similar, this product is like it but tailored specifically for educational purposes.
As for Jupyter Notebooks – ClassroomIO allows you to create an assignment and have a group of students work on it simultaneously without interfering with one another. (Maybe you can do this somehow in Jupyter, but I don't know how.) Also, it supports more languages and the flow is more like a regular console app.
Also, in Python (unlike TypeScript or PHP) you need to be sure that the code regularly passes type checking to have confidence in your type annotations.
I've dealt with my share of code with types that were almost correct but not really and it's been quite frustrating.
