It supports Python 2 and 3.  When you submit solutions to the exercises,
the system looks at the hashbang (#!) to check whether you are using
Python 2 or 3:

	#!/usr/bin/env python2

or

	#!/usr/bin/env python3

When none of these are present it defaults to Python 3.

The examples in the tutorial section (https://cscx.org/programming-basics)
are done so that they are compatible with both versions of the language.
So if you have either 2 or 3, you'll be able to follow the tutorial and
exercises.

I'll add this clarification in the setup section and the FAQ later this
week.
