The former, without a doubt. It says exactly the same thing, since lst 
can only be considered false when it is empty. Experienced Python 
programmers would scratch their heads at your second formulation.

I doubt there's much in it from a time point of view (though I know as I 
write this it will spur someone to use timeit.py to point out I am wrong).
