title: What's the best way to aggregate the boolean values of a Python dictionary?
body: <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>
