with the speed I get, because I am learning python, I think I could do

I write this :-

First of all, as Steve Holden mentioned, do look at xlrd. It's
awesome.
Second, for your (a) question, if you want an iterator, that's quite
easy:
matriz = iter(matriz)
matriz.next() # Discard the first one
for i in matriz:
This technique works really well, especially if you have sub-loops.

That's exactly what I was looking for!

Is there an elegant way to unget a line when reading from a file/stream
iterator/generator?
