What I am trying to do is compare two files to each other.

If the 2nd file contains the same line the first file contains, I want
to print it. I wrote up the following code:



correct_settings = open("C:\Python25\Scripts\Output
\correct_settings.txt","r")
current_settings = open("C:\Python25\Scripts\Output\output.txt","r")

for line in correct_settings:
        for val in current_settings:
            if val == line:
                print line + " found."


correct_settings.close()
current_settings.close()


For some reason this only looks at the first line of the
correct_settings.txt file. Any ideas as to how i can loop through each
line of the correct_settings file instead of just looking at the first?

=====================================
I think the problem is that it's actually only looping through
current_settings once; for the remaining lines in correct_settings,
current_settings is at EOF and produces nothing to be matched.

for line in correct_settings:
	if line in current_settings:
		print line + "found."

This may do what you want.
