Uninitialized value in Python?
<p>What's the uninitialized value in Python, so I can compare if something is initialized, like:</p>

<pre><code>val

if val == undefined ?
</code></pre>

<p>EDIT: added a pseudo keyword.</p>

<p>EDIT2: I think I didn't make it clear, but say val is already there, but nothing is assigned to it.</p>
