title: Object's unique identifier (translate from hexadecimal into decimal)
body: <p>I'm learning Python (classes at this momment). On <a href="http://openbookproject.net/thinkcs/python/english2e/ch13.html" rel="nofollow noreferrer">this</a> site (bottom of the page) first exercise (under 13.7. Exercises) says:</p>
  
  <blockquote>
    <p>Create and print a Point object, and then use id to print the object's unique identifier. Translate the hexadecimal form into decimal and confirm that they match.</p>
  </blockquote>
  
  <p>I need help with this because I'm not quite sure I understand what I have to do.</p>
  
  <p>If I do:</p>
  
  <pre><code>class Point:
      pass
  
  print Point()
  print id(Point)
  </code></pre>
  
  <p>I get this output:</p>
  
  <pre><code>&lt;__main__.Point instance at 0xb71c496c&gt;
  3072094252
  </code></pre>
  
  <p>So, should I do this first part of exercise like this or? And what now? I assume that this second line is decimal number (Am I right?). But what with the first line? How to translate it into decimal?</p>
