title: String formatting expressions (Python)
body: <p>String formatting expressions:</p>
  
  <pre><code>'This is %d %s example!' % (1, 'nice')
  </code></pre>
  
  <p>String formatting method calls:</p>
  
  <pre><code>'This is {0} {1} example!'.format(1, 'nice')
  </code></pre>
  
  <p>I personally prefer the method calls (second example) for readability but since it is new, there is some chance that one or the other of these may become deprecated over time. Which do you think is less likely to be deprecated?</p>
