How to read only a specific range of lines out of a csv file with python?

Question

How can I only read from line 5000 to 6000 in this csv file for example? At this moment "for row in reader:" loops through all lines of course.

So I have the lines:

with open('A.csv', 'rt') as f:
     reader = csv.reader(f, delimiter=';')
     for row in reader:
           response = urllib2.urlopen(row[12])

This code is used to open specific url links.

Because csv reader object supports iteration, you can simply use itertools.islice to slice any specific part that you want.

from itertools import islice

with open('A.csv', 'rt') as f:
     reader = csv.reader(f, delimiter=';')
     for row in islice(reader,5000,6000):
           response = urllib2.urlopen(row[12])
