An IPython notebook explaining how Python's super() works.
To use the notebook, clone the project and cd to the directory containing the .ipynb file. Then start the IPython (Python 3.x) notebook something like this:
% ipython3 notebook
This will (or at least should) pop up a new browser window for your notebooks, and one of the available notebooks will be named 'super_explained'. Open that up and go to town!
