title: Python file open() in Enthought Canopy fails with: "IOError No such file or directory"
body: <p>I'm running code under Enthought Canopy to open and read a file. It keeps telling me IOError.</p>
  
  <p>But I am pretty sure the text file name is right and it is in the same directory with the Python file, and the code works well in other IDEs like Python IDLE. Don't know what's wrong. Any suggestions?</p>
  
  <pre><code>inFile = open('words.txt', 'r')
  words = inFile.read().split()
  </code></pre>
  
  <p>fails with <code>IOError: [Errno 2] No such file or directory: 'words.txt'</code></p>
