Supported Python versions

[brettatoms]

What are the supported Python versions? Are there plans to support Python 3?

2.7.* for now, we'll support 3 when our dependencies do, there are many important ones that don't at the moment

For reference it looks like the main blockers are thrift and snakebite.

Yeah, that is painful but FWIW I think this list might be a little misleading since some of those packages support Python 3 but they just don't have their supported versions defined in their setup.py.
