Readers familiar with previous versions of IPython might notice that nothing has been said about the Notebook. That is because the Notebook has split off from the main IPython project. It is now a project on its own, named Jupyter, which can be found at https://jupyter.org/. As the IPython project grew, it was determined that it was trying to be too many things to too many people: a terminal, a Python kernel, a notebook, a parallel framework, and much more. The decision was made to split the project into two main parts, Jupyter and IPython, with IPython calving off into several subprojects.

As such, this book will focus on IPython and its interactive terminal. An overview of Jupyter will be provided in Chapter 11, Into the Future, but the primary focus will be on working with the terminal. This does not mean that graphical I/O will be neglected. The truth is far from it, in fact, as the terminal supports many quality graphics packages.
