FWIW, I would like to see a newsgroup or python-dev discussion for a 
more general solution to the problem for helpful repr's for iterators.  
In 3.0, lots of things return iterators, not just range().  

Before applying one ad-hoc patch, it would be helpful to think through 
how the issue should be handled across the whole language.  For 
example, perhaps pprint() should display general iterators with the 
<...> notation.  

For teaching and experimentation purposes, maybe the right answer is 
the make the command-line a bit smarter.  It already knows how to 
suppress None return values.  Perhaps, it should be taught how to 
display range objects and dict.items() and such.
