title: How to sort integers alphabetically
body: <p>How can I sort integers alphabetically? Like this:</p>
  
  <pre><code>integers = [10, 1, 101, 2, 111, 212, 100000, 22, 222, 112, 10101, 1100, 11, 0]
  </code></pre>
  
  <p>printed like this on Python console</p>
  
  <pre><code>[0, 1, 10, 100000, 101, 10101, 11, 1100, 111, 112, 2, 212, 22, 222]
  </code></pre>
  
  <p>I have tried this</p>
  
  <pre><code>def sort_integers(integers):
      return sorted(integers)
  </code></pre>
  
  <p>but I guess you have to do it this way</p>
  
  <pre><code>def sort_integers(integers):
      return sorted(integers, key = lambda....... )
  </code></pre>
  
  <p>I just don't know to what to write after the lambda?</p>
