title: Python: EOFError: EOF when reading a line
body: <p>This may be repeated, but none of the existing answers solved my problem.</p>
  
  <p>So, I'm using <code>Python 2.7</code>, and I get this error (title) whenever I try this:</p>
  
  <pre><code>number = int(raw_input('Number : '))
  </code></pre>
  
  <p>I tried this in Sublime Text 2, compileronline.com and in codecademy; it fails in the first 2 of this sites. It works on codecademy and in the terminal compiler, but I can't understand exactly why it is failing.</p>
