title: Use curly braces to initialize a Set in Python
body: <p>I'm learning python, and I have a novice question about initializing sets.  Through testing, I've discovered that a set can be initialized like so:</p>
  
  <pre><code>my_set = {'foo', 'bar', 'baz'}
  </code></pre>
  
  <p>Are there any disadvantages of doing it this way, as opposed to the standard way of:</p>
  
  <pre><code>my_set = set(['foo', 'bar', 'baz'])
  </code></pre>
  
  <p>or is it just a question of style?</p>
