title: How to correctly sort a string with a number inside?
body: <p>I have a list of strings containing numbers and I cannot find a good way to sort them.<br>
  For example I get something like this:</p>
  <pre><code>something1
  something12
  something17
  something2
  something25
  something29
  </code></pre>
  <p>with the <code>sort()</code> method.</p>
  <p>I know that I probably need to extract the numbers somehow and then sort the list but I have no idea how to do it in the most simple way.</p>
