What's the best way to aggregate the boolean values of a Python dictionary?
<p>For the following Python dictionary:</p>

<pre><code>dict = {
    'stackoverflow': True,
    'superuser': False,
    'serverfault': False,
    'meta': True,
}
</code></pre>

<p>I want to aggregate the boolean values above into the following boolean expression:</p>

<pre><code>dict['stackoverflow'] and dict['superuser'] and dict['serverfault'] and dict['meta']
</code></pre>

<p>The above should return me <code>False</code>.  I'm using keys with known names above but I want it to work so that there can be a large number of unknown key names.</p>
