import CSV file to Python

your row has 6 elements and you're trying to print the 2nd and the 9th. well, the latter does not exist, hence list index out of range (indexing starts with 0).

If you just want rows 2-8, use itertools.islice on the reader object:

import csv
from itertools import islice, izip

with open('highfrequency2.csv') as csvfile:
    freq = csv.reader(csvfile)
    # create islice object
    interest = islice(freq, 1, 8, None))
    # iterate over islice object getting row at a time
    for row in interest:
       print(row)

If you just want those two specific rows use a step of 6:

 import csv
from itertools import islice, izip

with open('highfrequency2.csv') as csvfile:
    freq = csv.reader(csvfile)
    interest = islice(freq, 1, 8, 6))
    for row in interest:
       print(row)

Or call next on the reader object after skipping the first line:

import csv

with open('highfrequency2.csv') as csvfile:
    freq = csv.reader(csvfile)
    next(freq)
    # create generator expression
    interest = (next(freq) for _ in range(7))
    for row in interest:
       print(row)

Or using enumerate:

 import csv

with open('highfrequency2.csv') as csvfile:
    freq = csv.reader(csvfile)
    interest = (row for ind, row in enumerate(freq) if ind in {1,7})
    for row in interest:
       print(row)
