| python.org has the tutorial for 3.0 complete already.
Python 2.x (2.6 currently) and 3.0 are different enough that a not-insignificant portion of the old-guard python folk are kinda ticked at the direction the language has gone (personally, the new string formatting stuff drives me batty).
But 3.0 was in part designed with people new to the language in mind and to that end, they've done a pretty good job with it as far as I've seen.
2.6 is going to have a lot of resources and it's a good place to start, but try the 3.0 tutorial first unless you're going to have to support 2.6 code immediately. If you learn the 2.x branch first, there are a few common things you'll have to unlearn that, in a pinch, you can import into 2.6 from 3.0 with the 'from future' directive if absolutely necessary. |
