If the files aren't terribly large (not tested):
correct_lines=open(r"C:\Python25\Scripts\Output" \
"\correct_settings.txt", "r").readlines()
current_lines=open(r"C:\Python25\Scripts\Output\output.txt",
"r").readlines()
for line in current_settings:
if line in correct_lines:
print line + " found"
This does what you asked for but somehow I don't think it is
what you want. I would suggest that you take a look at difflib.
Somththing along the lines of:
import difflib
correct_lines=open(r"C:\Python25\Scripts\Output" \
"\correct_settings.txt", "r").readlines()
current_lines=open(r"C:\Python25\Scripts\Output\output.txt",
"r").readlines()
delta=difflib.unified_diff(correct_lines, current_lines)
diffs=''.join(delta)
print diffs
Will show you the lines that are different and some lines
around it for context.
