Description

One prerequisite for using Python 3 is fixing all syntax errors across all our Python code. We should add a script that compiles every python files with Python 2 and Python 3 to verify that the syntax is ok. Once clean, this should run as part of GVO.

For example, Python has a compileall functionality that can be used:

python3 -m compileall {python file}

This is also a good time to add future as a pypi dependency (provides the futurize script and some libraries for writing py2/py3 code).
