title: naming dictionaries after list items
body: <p>I have a list like <code>list = ['foo', 'bar', 'baz']</code> and am running a for-loop over the items. each time I do so, I'd like to create a dictionary named after the list element currently being looped over. For example</p>
  
  <pre><code>for element in list:
      ('%s' + '_' + 'dict') % element = {}
  </code></pre>
  
  <p>which, of course, doesn't work, giving me the error:</p>
  
  <pre><code>SyntaxError: can't assign to operator
  </code></pre>
  
  <p>Any ideas?</p>
