Well, yes, sure... core programming concepts are the same regardless of language used and/or version.
However, from my experience, most students don't venture off on their own until after becoming very familiar with a language. Not all students are experimental enough to hack on personal projects for fun or what-have-you. I've actually had a fellow student tell me the Java class file he emailed me for a project would only run on Java 6 since that's what the lab had installed -- obviously wrong.
The point being -- students will intern what they are taught. They should be taught on modern versions/concepts so they intern modern ways of doing things. By teaching Python 2.x to students, you do them a disservice by teaching them the way Python "used to" do it... not how it "does it" now.
As an aside -- with all of the major Python libraries now ported to 3.x -- I see little to no reason anyone should ever learn Python 2.x, or use it (with the exception of the obvious legacy codebase support issue).
