Anyway, I’m really proud of how well DiP3 [Dive into Python 3, ks] came out. The only problem is that no one is using Python 3. I took a gamble last year that large libraries would port to Python 3 while I was writing. That didn’t happen. I think it’s pretty clear by now that that’s not going to happen anytime soon. Everyone who gambled on the glorious non-backward-compatible future got burned. Given my experience with HTML, you’d think I’d learn. Ah well.
So what are realist expectations? Python 2 as the future of a research language called Python 3?
