I don't think the OP is asking Sal to throw in multiple PEP explanations in each 10min video. But looking at it from an absolute beginner's point of view, you're going to assume that Sal is (at least at this point) the authoritative source of how to do things in Python. You're going to comment all your programs this way. It's going to be a habit you have to unlearn later, or worse spread to others. The real issue is that there is already a clearly defined way to do these things. If you've got any meaningful experience with Python, you should be following at least the spirit of the PEPs. I don't think that's unreasonable for Sal to do.
