Hi. Before we can help you we need to know a little more of your problem. Are you looking for duplicate lines in the file, or duplicate strings defined in some other way? How big is the file you want to read (how many lines or strings do you want to compare)? There are modules which will help you write your program, but exactly how you go about it depends on the details of your problem.
