something like:

[x*y-z for (x,y,z=0) in (1,2,3), (4,5), (6,7,8)]

instead of the less elegant explicit loop version that has to check for the 
length of each sequence.
What do you think ?

How did you get the data in that format in the first place? It looks a bit strange to me. Wouldn't it be easier to fill in default values when you gather data as opposed to when you use it?
