The ``Hello, world'' of csv reading is

    import csv
    reader = csv.reader(open("some.csv", "rb"))
    for row in reader:
        print row

To print just the first and last columns of each row try

    import csv
    reader = csv.reader(open("some.csv", "rb"))
    for row in reader:
        print row[0], row[-1]

The corresponding simplest possible writing example is

    import csv
    writer = csv.writer(open("some.csv", "wb"))
    for row in someiterable:
        writer.writerow(row)
