Python 3.x in python (x, y)?

I am creating an environment similar to Matlab, so I downloaded the latest version of python (x, y) with all the modules that come with it, and downloaded python 3.4.1. Is python (x, y) running the latest version of python? I noticed that the python (x, y) shell does not automatically calculate the math operations in the floats that I am reading is the difference between python 2.x and 3.x. Do I just need to wait for the new version (x, y) or am I missing something here?

from __future__ import division
