I think I zoned this part of the discussion out, but I've written code
like this:
lineiter = iter(aFile)
for line in lineiter:
if sectionmarker in line:
break
parseSection1Line(line)
for line in lineiter:
if sectionmarker in line:
break
parseSection2Line(line)
(though, not *quite* that regular...)
This is, to me, neat and clear. I don't find the idea that iterators
are tied to exactly 1 for loop an improvement (even though they
usually will be).
Cheers,
mwh
