On: Key differences between Python 2.7.x and Python 3....

I know that the best way to learn is "see one, do one, teach one" but I wish you'd put more effort into learning the language before teaching it.

The python.org tutorial and FAQ have answers to these questions.

I think it's unethical to tell a student, "just because" instead of, "I don't know why."

You're replying to the wrong person. I'm not the one who is doing teaching, I'm just the guy who corrects the teacher who hates Python 3 (for wrong reasons) ;)

Sorry about that.
