Jupyter Notebooks

To install: Install (instructions at jupyter.org). Note that pip or pip3 install works. It’s on that page, after the Anaconda part.

You do not have to use Anaconda, which installs a lot of extra things.

You can install into a virtualenv.

After installing (with virtualenv activated, if you installed it that way), in Terminal, at bash prompt:

jupyter notebook

On Mac OS and Chrome, a new browser tab opens automatically, and you’re in the same folder where you were in the Terminal. If you have someone else’s notebook or a folder full of notebooks, you can toss them into that folder using Finder, just like any files.

Above: Two folders and one notebook file. Below: A notebook, open for work.

Create a new notebook file: The New button is on the far right side.

The thing I find hard to remember: You have to press Shift-Return to run the code in one of the boxes, or to save markdown you wrote. On the Cell menu, there’s an option to Run All.

Menus and icons: Very self-explanatory. Explore them.

File menu: “Revert to checkpoint” lets you roll back to the previous save.

File menu: “Close and Halt.” Saves the current notebook file and closes it.

To quit Jupyter, go to the Terminal and Control-C (not Command).
