My rule of thumb for making a judgement on Python performance is never 
assume anything, ever.  In using Python for well over 10 years my gut 
instinct has never been correct on this matter.  The only thing to do is 
profile your code and then seek the answers online, as you can guarantee 
someone else has already been there, seen it, done it and got the t-shirt :)
