Newb question about %02d %04d

Another thing I wanted to ask about. Maybe its nothing. But I've read a few different places, people saying "Well python 3 isn't really python." and then they don't elaborate much. At first I just wrote it off as one of those things people say but I've seen it enough now to make me curious as to why they'd say that. It doesn't seem all that different to me, from python 2. Certainly not enough to say that.
