In this set of chapters, we've just scratched the surface of using IPython to enable data science tasks. Much more information is available both in print and on the web, and here I'll list some other resources that you may find helpful.
Finally, a reminder that you can find help on your own: IPython's ?
-based help functionality (discussed in Help and Documentation in IPython) can be useful if you use it well and use it often.
As you go through the examples here and elsewhere, this can be used to familiarize yourself with all the tools that IPython has to offer.
