Testing on multiple python environments

If I have a project that is meant to build/run on multiple versions of python (2.7,3.x) how can I (assuming I can) have the same set of tests executed for both of the current branches of the 2.7 line as well as the 3.x? Any recommendations? Love the whole idea of circle-ci! It’s just awesome.

Sorry for the delay here. I explained a few ways to achieve that in this post, could you please check it out?

Thank you for your kind words.
