linecache and comparison with input

Say I've got a file called 'testfile' that contains the following three
lines:

foo
bar
baz

And a script that goes like this:

#!/usr/bin/env python

import random
import sys
import linecache

rnd = random.randint(1,3)
line = linecache.getline('testfile', rnd)

print line

gss = raw_input('Enter line: ',)

if gss == line:
    print 'yes'
    sys.exit()
else:
    print 'no'


Even if the right word is entered, the script always prints `no'. Can
anyone explain why this happens?
