Well, readlines/split really isn't bad. So long as the file fits comfortably in memory: fi = open(file) lines = fi.readlines() evens = iter(lines[0::2]) odds = iter(lines[1::2]) csv1 = csv.reader(evens) csv2 = csv.reader(odds) The trick is that the "csvfile" in the CSV object doesn't have to be a real file, it just has to be an iterator that returns strings. If the file's too big to fit in memory, you could piece together a pair of iterators that execute read() on the file appropriately. -- http://mail.python.org/mailman/listinfo/python-list
