Yeah, but one of the issues is that some very popular packages for Python were already development-dead for years.
PIL is a good example; the last actual PIL release was in 2009. We now have a great fork that works (Pillow), but PIL is not the only dead package that's still in active use. There are quite a few others, too.
This is one of the issues I see that need to be corrected. I have attempts at migrating to 3, that failed miserably. One happened to be while teaching my son Python with "Python for Kids" that ended up making the experience difficult and the others that ended up causing conflicts in various OS dependencies.
I have to say, Python is my favorite language still (at least 2.7), and I hope the community can get it back in line. I can see JS, NodeJS and Python being my core technologies, but this issue with 3 is squashing my dream.
