This repository contains the full listing of IPython notebooks behind the [Python Data Science Handbook](http://shop.oreilly.com/product/0636920034919.do), including all text, code, and figures. The book was written and tested with Python 3.5, though older Python versions (including Python 2.7) should work in nearly all cases.
The book was written and tested with Python 3.5, though older Python versions (including Python 2.7) should work in nearly all cases.
The book introduces the core libraries essential for working with data in Python: particularly [IPython](http://ipython.org), [NumPy](http://numpy.org), [Pandas](http://pandas.pydata.org), [Matplotlib](http://matplotlib.org), [Scikit-Learn](http://scikit-learn.org), and related packages.
Familiarity with Python as a language is assumed; if you need a quick introduction to the language itself, see the free companion project,
