There are many python distributions, many python versions (2.7.xx
, 3.nn
) and… many ways to use python:

Using an ipython notebook means that:

jupyter notebook
, but only do this if you want to work locally on your desktop/laptop! See the next section for working on a remote computerjupyter notebook
command will start the notebook server, and it will automatically start a web browser on the same computer. That's OK on your local computer, but on a remote server, the browser will probably seem to be slow (and out of date) and will use unnecessary resources of the server. This will be frustrating for you and the other users of the server^C^C
(2x CTRL-C
). Otherwise the server and the python processes started by the server will keep on using resources on the computerjupyter notebook
The ssh tunnels will allow you to connect a web browser running locally on your computer to a notebook server running on a remote server
