What does this mean in my boss's python code?
<p>This is the code :</p>

<pre><code>modulename, classname =  settings.APP_USER_CLASS.rsplit('.',1 )
modulemeta = __import__(modulename, globals(), locals(),  [classname])
</code></pre>

<p>I don't understand this:  <code>__import__(modulename, globals(), locals(),  [classname])</code>  mean ,</p>

<p>so what is it ,</p>

<p>thanks</p>
