Can you please get on and fix this if you're going to deprecate Python 2.0.  It's unkind on your users to deprecate the old version before you've fixed basic regressions like this in the new one.  Just to be clear, I am attaching the code that reproduces this (tmp.py).   Run it with Python 2 and 3 to see the difference.  I will not fill in your agreement form, and no I will not provide my reasons, but you don't need it, it's a one-line fix.
