> Ah, thank you Dan. I followed your advice ... the working code:
with fileinput.input(sys.argv[1:]) as f:
reader = csv.DictReader(f)
for row in reader:
for key, value in row.items():
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.
