Ok the example I gave here wasn't written as I had it in my head.. you are
right, the example only had 1 sentence.
Inputs:
List1 ['a.exe','b.exe',c.exe']
List2 ['A.exe',B.eXe',c.EXE']
for item in List1:
if item in List2:
print item + " " + list2thing that matched.
I can't force to upper or lower, that would break the already working code..
Its just this darn output for list2 that isn't working.
I tried the suggested list.index(item) but that wont work if there isn't a
match.
Right now my code works when there is a match, and if there isnt'...
It also works for renaming the actual file to match the file call from the
document.
I'm about to take the display out, since I dont honestly care that it works,
but now that I've been working with it I'm being stubborn and want the darn
thing to show me =P
