I don't think so -- Python has been around a long time and really grew up with the web during the 2.x series, thus, libraries have been slow to move to 3.x and adoption of 3.x has been slow because of that. Also, 3.x didn't really add any new killer features either -- I think maybe that is starting to change however with some cool new stuff only landing in 3.x (asyncio, type annotations are coming, etc).
