There may be a language barrier here (probably on my side), but
I think that the OP was asking for something more elementary.

You have:


DATA DATA
DATA DATA DATA DATA
DATA DATA DATA
DATA DATA
DATA DATA
DATA DATA DATA
DATA DATA
DATA DATA


Read the file and 'jump' to line four, and then do:

	line.split()[3]

and get "kind of 'index out' error"

So he could at least do:

l = line.split()
if len(l) > index:
	data = l[index]
else:
	data = None

Assuming index counts from zero.

Or perhaps I miss the point entirely.
