[Tutor] newb help reading lines from csv

[Dewhirst, Rob]

import csv
ifile = open('test.csv', "r")
reader = csv.reader(ifile)
for row in reader:
	print row
for row in reader:
	print row
ifile.close()

This is a simplified version of what I am trying to do - loop through
a CSV file twice.  Why does the second for loop not execute at all?
The first one prints the rows of the file just fine.
