Python 2.x versus Python 3.x

Preface > Python 2.x versus Python 3.x
At the time of writing, there are two supported versions of Python in
common usage: Python 2.7.x and Python 3.3.x. In the first few
offerings of this course, we used Python 2.7.x. Our reason for
choosing this somewhat older version was because some of the libraries
used later in the course were available only for Python 2.7.x.
As of the 2013/14 academic year, we will use Python 3.3.x, as all required
libraries have now been ported to this more recent version.
