Where is the __builtin__ module in Python3? Why was it renamed?
<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__
&gt;&gt;&gt;
</code></pre>
