Short circuit evaluation assignment in python?
<p>Ruby supports this:</p>

<pre><code>name = name || "default"
</code></pre>

<p>If I try it in python: </p>

<pre><code>name = name or "default"
</code></pre>

<p>Interpreter reports:</p>

<pre><code>NameError: name 'name' is not defined
</code></pre>

<p>What is the equivalent of the short circuit evaluation assignment in python?</p>
