You may read the "What's new?" documents for 3.0 and 3.1:
If you're learning Python the differences aren't so important now (the  
most obvious being that the print statement becomes a function). If you're  
using a book covering Python 2.x, install the latest on that series  
(2.6.2). Support for Python 3 is increasing but many 3rd party libraries  
have not been ported yet.

Look in the wiki:
or search past messages in this list. The topic arises every two months or  
so. There is no definitive answer.

Ask the IPython team; but unless a project explicitely states that it's  
compatible with Python 3, you should assume it isn't.
