From the webpage:
Tutorials on the scientific Python ecosystem: a quick introduction to central tools and techniques. The different chapters each correspond to a 1 to 2 hours course with increasing level of expertise, from beginner to expert.
In PDF format, some six-hundred and fifty-seven pages of top quality material on Scipy.
In addition to the main editors, there are fourteen chapter editors and seventy-three contributors.
Good documentation needs maintenance so if you improvements or examples to offer, perhaps your name will appear here in the not too distant future.
Enjoy!
