sorting elements out of the list
<p>I need to step some elements from a list (in this case n)
I has also another list ( o list)</p>

<pre><code>n=['A','B','C','D','E']
o=['A','B','C','D','E','AS','sd','Z','R']
n.sort()
</code></pre>

<p>Now if I use this code:</p>

<pre><code>for o in sorted(n): 
</code></pre>

<p>The code is run for <code>'A','B','C','D','E'</code>.</p>

<p>I need to run the for code but just only <code>'AS','sd','Z','R'</code> items.</p>

<p>Something like : run the code for items from o list without items from n list</p>
