Yup, basically a readability thing.  I also tend to find that if I 
actually declare the function, I can often find a way to refactor things 
to make that function useful in more than one place.

Additionally, 'lambda' is on Guido's regrets list, so I'm avoiding it's 
use in case it gets yanked for Python 3.0.  I think most code can be 
written now without it, and in most cases code so written is clearer. 
Probably worth looking at is a thread I started that went through some 
stdlib uses of lambda and how they could be rewritten:

Many were rewritable with def statements, list comprehensions, the 
operator module functions, or unbound or bound methods.
