I hope these are small files, the algorithm you wrote is not going to run well as file size gets large (over 10,000 entries)
Have you checked the space/tab situation? Python uses indentation changes to indicate the end of a block, so inconsistent use of tabs and spaces freaks it out.
Here are a couple questions:
Are these always numbers?
Do the files have to remain in their original order, or can you reorder them during processing?
How often does this have to run?
Do you have to "comment" the duplicate, or can you remove it?
Are there any other requirements not obvious from the description below?
