Testing with multiple Python versions

I’d like to be able to have CircleCI run my tests first with the latest Python 2 and then with the latest Python 3. Can I configure CircleCI to do this? I need to ensure compatibility across both versions.

There’s a great blog post on how to do this with CircleCI written by one of our customers: https://ben.fogbutter.com/2016/02/20/testing-multiple-python-versions-on-circleci.html
