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) ;)
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."
