This is a Python 3.4 virtual environment. This is AWESOME for us because it means we should no longer need to depend on unique machines' Python modules matching up. For example, I have a Python module SciPy on my machine that you might not have which will make some of my code fail to run for you.

A virtual environment (virtualenv or venv) fixes this by running as an independent little Python installation that we can all run off of. Pull this down and use this Python directory as your Eclipse / whatever IDE's Python interpreter.
