title: LPOP or delete in redis list
body: <p>I have a redis list </p>
  
  <pre><code>a, b, c ,d ,e ,f g, h
  </code></pre>
  
  <p>In my callbacks to a function I get the index for element and I want to delete that index.</p>
  
  <p>LPOP and RPOP are not working for me. How can I delete an element based on index and not value in redis?</p>
  
  <p>thanks</p>
