title: Check for False as any value in a dictionary
body: <p>I have the following dict:</p>
  
  <pre><code>default_wallart = {
      "parkinglot":False,
      "ferrari":False,
      "roadtrip":False,
      "sincity":False,
      "peekaboo":False
  }
  </code></pre>
  
  <p>I update this to <code>True</code> when something happens and triggers it. What I would like to be able to do, though, is check if <em>any</em> of the values in the dict returns False (and if they do return False for any of the values do one thing, and if not, do something else).</p>
  
  <p>So... how would I go about this? Would be nice if I could do this in a one-line check, but if not, I can work around that.</p>
  
  <p><strong>Note:</strong> this is for Python 2.7x</p>
