We have just released a new version of the "scipy lecture notes": http://www.scipy-lectures.org/
These are a consistent set of materials to learn the core aspects of the scientific Python ecosystem, from beginner to expert. They are written and maintained by a set of volunteers and published under a CC-BY license.
Highlights of the latest version includes:
* a chapter giving a introduction to statistics in Python * a new layout with emphasis on readability including on small devices * fully doctesting for Python 2 and 3 compatibility
We hope that you will find these notes useful, for you, your colleagues, or your students.
