Be sure your current working directory is your desktop.

import os
print os.getcwd()

Otherwise specify the full path to the text file. r'c:\users....\mort.txt'

At first I was just  using 'mort', which is what appears on my desktop,  but  it was suggested to  me that I should include the extension  .txt, which I have verified is the correct extension, so that's not the problem anymore.  I have  in fact tried this with a number of files  and I get the same message every time.    I am using   Python versus  3.2.2. ,  on a MAC  with system    OS  10.6.8 .
