title: Where is the __builtin__ module in Python3? Why was it renamed?
body: <p>I was curious about the <code>__builtin__</code> module and how it's used, but I can't find it in Python3!  Why was it moved?</p>
  
  <p>Python 2.7</p>
  
  <pre><code>&gt;&gt;&gt; import __builtin__
  &gt;&gt;&gt;
  </code></pre>
  
  <p>Python 3.2</p>
  
  <pre><code>&gt;&gt;&gt; import __builtin__
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named __builtin__
