So, what I hear you saying is that (citing, "In this case, there's no further body, so it's going to be the same as "pass" (which > means "do nothing")") that the else block is not entered. For exma Seems like a cut-off paragraph here, but yes. In a try/except/else block, the 'else' block executes only if the 'try' didn't raise an exception of the specified type(s). > Do you mind elaborating on what you meant by "compatible headers?". The files that I am processing may or may not have the same headers (but if they do they should add the respective values only). > Your algorithm is basically: Take the entire first file, including its header, and then append all other files after skipping their first lines. If you want a smarter form of CSV merge, I would recommend using the 'csv' module, and probably doing a quick check of all files before you begin, so as to collect up the full set of headers. That'll also save you the hassle of playing around with StopIteration as you read in the headers. ChrisA
