Wrong on both counts. ;-) Python 3.0 is not a rewrite. It's based on the 
same code base as the 2.X line, but with a lot of the old deprecated 
things removed. And, while Python 3.0 is allowing itself to break 
backwards compatibility, at least that the Python level, it should be 
largely compatible with the 2.X line. There will be some breakages, but 
(1) they shouldn't be too extensive and (2) there will be utilities to 
help you update your code. In many cases, it will be possible to write 
code that works in both Python 2.X and 3.0.
