with fileinput.input(sys.argv[1:]) as f: reader = csv.DictReader(f) for row in reader: if fileinput.isfirstline(): continue for key, value in row.items(): pass #processing I was hung up on that continue on firstline, because I thought that would skip the header of the first file. I think now the csv.DictReader(f) command consumes it first. -- https://mail.python.org/mailman/listinfo/python-list
