Chapter 3 Jupyter Notebook Overview

3.1 Interface

Jupyter Notebook provides a very simple and user-friendly interface, including Menu bar, Toolbar and Cell. A notebook consists of a sequence of cells. There are three types of cells in Jupyter Notebook.

  • Raw Cell: Raw cells provide a place where you can write anything that you don’t want to be executed by the notebook.

  • Markdown Cell: Markdown cells can be executed and provides documentations for your notebook.

  • Code cell: A code cell allows you to edit and write new code. When executed, the code is sent to the kernel associated with the notebook. The execution results are returned and displayed in the notebook as the cell’s output.
