Python 3 For Python 2 Users

[Tim Daneliuk]

I code in Python 2.x intermittently and have only casually watched the
3.x development discussions. Now it's time to get up to speed.
Has someone written a tutorial for people in my situation. Yes, I've
looked at the release notes, but I'm looking for something that
motivates all the major changes to give me a better sense of the
Gestalt of the new language.

TIA,

All classes are subclasses of object.
Text strings are unicode.
Miscellaneous deletions.
Some new stuff, especially ABCs, though it may be awhile before they
really inpact Python practice.
