If you can read 2 columns here, read 4 columns at a time. Access by their index. Assuming it's a CSV file,

import csv
rows = []
with open('file.csv') as csvfile:
    reader = csv.reader(csvfile, ...)
    for row in reader:
         item_amount1 = row[1:3]
         item_amount2 = row[3:5]
         rows.extend([item_amount1, item_amount2])
