Personally I would immediately discard the header row once and for
all, not again and again on every operation.
Well, perhaps, but I need the header row to stay in place to write the
list to a csv when I'm done
That's no problem, just write the header row separately.
Do this at the beginning:
header = [Record._make(fieldnames)]
records = [Record._make(row) for row in rows]
and then to write out the file:
writer = csv.writer(outputfile)
writer.writerow(header)
writer.writerows(records)
I don't even think there's any need to store the field names anywhere
else than in fieldnames. So unless I'm missing something, just do this
at the beginning:
fieldnames = next(rows)
Record = namedtuple("Record", fieldnames)
records = [Record._make(row) for row in rows]
and this at the end:
writer = csv.writer(outputfile)
writer.writerow(fieldnames) # or writer.writerow(Record._fields)
writer.writerows(records)
