Here's a sketch of how one of my projects handles that situation.
I think the index variables are invaluable documentation, and
make it a bit more robust. (Python 3, so not every bit is
relevant to you).
with open("today.csv", encoding='UTF-8', newline='') as today_file:
reader = csv.reader(today_file)
header = next(reader)
majr_index = header.index('MAJR')
div_index = header.index('DIV')
for rec in reader:
major = rec[majr_index]
rec[div_index] = DIVISION_TABLE[major]
But a csv.DictReader might still be more efficient. I never
tested. This is the only place I've used this "optimization".
It's fast enough. ;)
