Converting strings to integers then ordering them in an list with strings
<p>I have the following list and I need to order them from biggest to smallest names and numbers. </p>

<pre><code>['joe:  5', 'ed:  9', 'joe:  7', 'ed:  8']
</code></pre>

<p>I'm having the following problems:</p>

<ol>
<li>Converting the numbers from strings to integers to order it.</li>
<li>Ordering them with the correct string.</li>
</ol>

<p>So my end result should be this:</p>

<pre><code>['ed:  9', 'ed:  8', 'joe:  7', 'joe:  5']
</code></pre>
