Books on Python now vs in 8 months.

[Phil Voris]

I've been considering learning Python as a means of getting insight into
OO thinking.  I have been reluctant to by the snake or rat books because
I have read that future versions of Python -- mayber even versions as
early as later this year -- will be radicaly different and in some ways
backwards incompatible.  I ask myself if it's worthwhile to learn it one
way if it will change so quickly.  Does anyone have insight as to how
much it's _really_ going to change...?
