Installing Python 3.3

So there are two ways of installing python such that the nice Mathematica-like iPython notebook environment works. In the above, it's hardcore console. Here's a related blogpost. Here's a better one. For me I installed Python 2.7 on an older Mac.

I needed to say "pip install ipython[all]" instead of what's in the video.



Then running "ipython notebook" worked. You also need to "pip install" numpy, pandas etc.



Alternatively, and avoiding console for the most part, one may go to Anaconda website. There they have a file you can download for consoleless installation. Ideally "ipython notebook" console command then just gives you what you want.
