title: Coverting all the list elements to string using Python?
body: <p>I have a list:</p>
  <pre><code>roll = [1, 2, 3]
  </code></pre>
  <p>For converting each of the element into a string, can we directly do <code>roll = str(roll)</code> rather that iterating over it and calling <code>str()</code> on each element? Is this a correct way?</p>
  <p>I am new to Python, any hint in the right direction will do!</p>
