Without your data file I can't advise, but here's a couple of things
to try. I see you've tried displaying the values:
#print sp[9], sp[10]
Try this version:
print repr(sp[9]), repr(sp[10])
That'll make it obvious if, for instance, there are leading/trailing spaces.
The other thing you may want to consider, if the values are supposed
to be integers, is to convert them to Python integers before
comparing. Currently, you're working with strings. Replace this:
if sp[9] == sp[10]:
with this:
if int(sp[9]) == int(sp[10]):
That will consider "1" and "1 " to be the same, since they'll both be
parsed as the integer 1. Alternatively, consider what Tobias said and
explicitly strip spaces. Either way, displaying repr() of the strings
(or printing the whole of sp, as Tobias suggests) will show you what's
needed.
