I have now finished my book on an "Introduction to Statistics with Python", and it will appear with Springer approximately in January 2016. The corresponding git-repo - which is essentially the continuation of this repo - is
https://github.com/thomas-haslwanter/statsintro_python.git
which also contains the IPython Notebooks that go with this manuscript.
For the book the manuscript has been significantly extended, corrected, and improved. For a short time, an outdated version of the manuscript will still be available under http://work.thaslwanter.at/Stats/html/ I hope that when I have to take that manuscript offline, I will be able to interest you in the full version of the book.
Python rocks - also for statistical tasks!
