title: Comparing elements in two lists
body: <p>I have two  <code>lists</code>. Say one is <code>[6,4,2,1]</code> and the other is <code>[1,3,5,7]</code>. I need to  compare elements of respective positions (first element of first list compared with first element of second list). I need a third <code>list</code> such that it tells how many elements in first list are greater than elements of second list.For example when the above two lists are compared,the third list should be like <code>[2]</code> ( because <code>6 &gt; 1</code> and <code>4 &gt; 3</code>). How can I do this </p>
