The Jupyter notebook is an open source semi language agnostic programming development environment aimed at simplifiying the creation and sharing of documents that contain live code, figures, and explanatory text. The Jupyter package is installed by default as part of the Anaconda environment and can be updated using the conda package management system.

Executing Code in a Notebook

1. To open a jupyer notebook, first open a windows or OSX terminal.

2. Via the command line, navigate to the folder in which you would like to open the notebook.

3. Then type the following in your terminal:

jupyter notebook

4. In your default web browser (e.g. Firefox, Chrome, or Safari), you should now see a window that looks like this.

5. To open a new notebook, navigate to the New drop down menu in the upper right corner and select Python 3 from the new menu.

6. This is what an empty Jupyter notebook looks like:

7. Rename the notebook by clicking on the Untitled at the top of the page. That will spawn this window:

8. The light gray boxes are Python interpreter cells in which code can be executed. Here, we write the code print("hello world").

9. To run the the code, we press <shift> + <enter>. The results are printed in the white cell underneath the code cell.

10. After a cell is executed, Jupyter notebook automatically adds a new cell underneath:

Cell Menu

A Jupyter notebook consists of cells. Each cell can contain code or text. The menubar for managing these cells is at the top of the notebook under the file menu. Hovering over the menu items yields their function. The menubar looks like this:

icon	function
	save the notebook
	insert cell below
	cut the selected cells
	copy the selected cells
	paste the selected cells
	move selected cells up
	move selected cells down
	execute code in cell
	terminate execution of cell
	restart notebook
	restart notebook and execute all cells
	type of cell (e.g. code, markdown, raw, etc)

Jupyter notebook also provides a set of keyboard shortcuts for managing these cells. You can read more about them at http://jupyter-notebook.readthedocs.io/en/stable/examples/Notebook/Notebook%20Basics.html#Keyboard-Navigation
