title: input() error - NameError: name '...' is not defined
body: <p>I am getting an error when I try to run this simple script:</p>
  <pre><code>input_variable = input(&quot;Enter your name: &quot;)
  print(&quot;your name is&quot; + input_variable)
  </code></pre>
  <p>Let's say I type in &quot;dude&quot;, the error I am getting is:</p>
  <pre class="lang-none prettyprint-override"><code>  line 1, in &lt;module&gt;
      input_variable = input(&quot;Enter your name: &quot;)
    File &quot;&lt;string&gt;&quot;, line 1, in &lt;module&gt;
  NameError: name 'dude' is not defined
  </code></pre>
  <p>I am running Mac OS X 10.9.1 and I am using the Python Launcher app that came with the install of Python 3.3 to run the script.</p>
