title: How to read user input until EOF?
body: <p>My current code reads user input until line-break.
  But I am trying to change that to a format, where the user can write input until strg+d to end his input.</p>
  
  <p>I currently do it like this:</p>
  
  <pre><code>input = raw_input ("Input: ")
  </code></pre>
  
  <p>But how can I change that to an EOF-Ready version?</p>
