Even if language permits
sum(x*w for x, w in zip(x, w))
would seem confusing for anyone watching the code
Maybe
sum(xi*wi for xi, wi in zip(x, w))
would be more appropiate

Thanks Will, the 2.4 expression looks really nice.

Suppose I have a list of n floats x and a list of n floats w and I want
to compute x[0]*w[0] + .. + x[n-1]*w[n-1].
Is there some elegant expression (perhaps using lambda) to have it done
in one statement ? As in :
y = lambda x,w : ...
I ask because the way I am doing it now :
y = 0
