Try putting some debug print statements in - for example 
print the option filenames to prove you got them  ok, 
print progress markers like adfter opening the files
Then print a message for each string found..

One thing you probably need to do is strip() the newline character 
from the end of a. Otherwise you will be searching for strings 
ending in newline. But if that  were the problem all the tests 
should fail and you should get a lot of output!

It is more readable if you put some spaces in!

 if found == -1:

HTH,
