A first look at the Jupyter user interface

We can jump right in and see what Jupyter has to offer. A Jupyter screen looks like this:

We see the URL of the page, http://localhost:8888/tree. localhost is a pseudonym for a web server running on your machine. The website we are accessing on the web server is in a tree display. This is the default display. This conforms to the display of the projects within Jupyter. Jupyter displays objects in a tree layout much like Windows File Explorer. The main page lists a number of projects; each project is its own subdirectory and contains a further delineation of content for each. Depending on where you start Jupyter, the existing contents of the current directory will be included in the display as well.
