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?

line = linecache.getline('testfile', rnd)

print line

Try print repr(line) ...

gss = raw_input('Enter line: ',)

and print repr(gss) ;)

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

Then you will see, that getline returns the line *including the newline
character*, while raw_input does not. Use line.strip('\n') to remove
trailing newline characters from the return value of getline.

Ah, thank you. I did notice that getline left a trailing newline, but I
didn't realise raw_input didn't. Ooops.
