[Programming] Nice new way of learning how to program

There's this cool tech called Jupyter that allows you to make documents called "notebooks" where you can put both markdown and executable code (a lot of programming languages supported).

This video I'm watching now demonstrates this:

I've also read that Github and Google Drive support it, though not sure how specifically.

Edit: note that Jupyter is not just for teaching programming, just wanted to note that.
