Something like this?
import csv
reader = csv.reader(csvfile)
header = None
paints = {}
colorants = {}
for line in reader:
if not header: header = line
else:
row = dict([header[i],item) for i,item in enumerate(line)])
name = row['Color Name']
colorant = row['Colorant']
if not name in paints:
paints[name]=db.paint.insert(name=name)
if not colorant in colorants:
colorants[colorant]=db.colorant.insert(name=colorant)
db.paint_colorants.insert(paint_id=paints
[name],colorant_id=colorants[colorant])
