What is a notebook?
A notebook is a document that does things. It looks like a web page -- text, headings, images. But between the text sections, there are cells that run code. You click a play button, the cell runs, and the result appears right below it.
You don't need to write code
You don't write the code. We've already written it. Your job is to fill in a form, pick an option from a dropdown, or type a question -- then click play.
