What you need for this book
The code is written exclusively in Python 3. Python 3 is, in many aspects, not compatible with Python 2.x [j.mp/p2orp3]. The focus is on Python 3.4.0 but using Python 3.3.0 should also be fine, since there are no syntax differences between Python 3.3.0 and Python 3.4.0 [j.mp/py3dot4]. In general, if you install the latest Python 3 version from www.python.org, you should be fine with running the examples. Most modules/libraries that are used in the examples are a part of the Python 3 distribution. If an example requires any extra modules to be installed, instructions on how to install them are given before presenting the related code.
