How about we help you here.. So if you want to compare by year, you want to read all the rows in and perform some math, because I can't help myself, I push this into sqlite at least but that's probably overkill for you (besides the limitless benefits:)). You want to store some state while you iterate over each row in the csv, appending data, then finally performing some statistical math on the collection. You will do this for each file, then finally aggregate your results. jlc -- https://mail.python.org/mailman/listinfo/python-list
