Line indexing in Python

[seafoid]

Hi Guys,

It has been point out that it is difficult for anyone to provide suggestions
if I do not outline more clearly my input file and an example of what I wish
to do with it (Thanks Rory!).

I mentioned it in this thread (Is creating different threads bad etiquette?
If so, lesson learned!):

Hope you guys may have some suggestions as I am stumped!

Thanks,
Seafoid :-)
