Leaving out third-party open-source projects I contribute to, and projects I've been involved with as part of my work (both open and private), and just focusing on code from my own personal Python packages: By count of lines, 0.04% of Python code I've published exists only to deal with 2 vs. 3 issues. Of that code, 34% consists of importing and applying a decorator from Django that handles setting up either __str__() or __unicode__() on a Django model as appropriate. Tellingly, there are exactly two lines I could find that aren't that decorator and which deal with a str/unicode issue. And that's in code which doesn't just run on Python 3, it supports 2 and 3 in the same codebase.
