Almost all the Python code I've written in the past year has been in Python 3. The libraries you mention have been ported already, as have many other important ones, such as sqlalchemy, lxml, httplib2, and imminently, Django.

Very early on I had plenty of headaches where some library I needed was Python 2.X only, but that's becoming increasingly rare.
