It's not, other than that mine is shorter and less readable :P

My point of demonstrating the use of partial() though (this is in response
to Christian also) is that along with 2.4 functions such as itemgetter()  
and attrgetter() and list/generator comprehensions, it will help remove
the need for nearly all uses of lambda functions or their equivalent 
nested functions.
