What Is Python 3000?
The next major Python release
To be released as Python
The first one in a long time to be patible
But pletely different or unusual
Concept first formed around 2000
Py3k nickname was a play on Windows 2000
Goal: to correct my early design mistakes
Those that would require patibility to fix
Reduce cognitive load for first-time learners
Work and thinking started for real last year

Activity Since Last Year
Lots of design discussions
(too many, if you ask me :-)
Some PEPs were written
(but not enough…)
Lots of code was written
(just the right amount!)
(but we're not done yet!!)
