title: List comprehension to access a nested list within a list only in one index
body: <p>What I need is to access an index of a nested list to filter the elements from another index in a list of tuples...
  For instance I have the following sample data:</p>
  <pre><code>samples = [('waterfall03', 9)] 
  
  distances = [('waterfall03', [12.03400784892136, 13.17207261956732, 13.91981431878607, 13.095577523116825, 13.405988675235129, 13.144871284931902, 13.597874214619402, 12.731745772059295, 13.90083238519232, 0.0])]
  </code></pre>
  <p>So in this case I have the sample waterfall03 where I have the number 9, which is the index to be removed from the index number 1 from the list of tuples in the list distances... i.e. I want to get a list as follows <code>[12.03400784892136, 13.17207261956732, 13.91981431878607, 13.095577523116825, 13.405988675235129, 13.144871284931902, 13.597874214619402, 12.731745772059295, 13.90083238519232]</code></p>
  <p>I have written the following code which is not working</p>
  <pre><code>distances = [[n for j, n, m in enumerate(zip(subarray, samples)) if j != m] for i, subarray in enumerate(distances) if i == 1]
  </code></pre>
  <p><strong>Expected output</strong></p>
  <pre><code>distances = [('waterfall03', [12.03400784892136, 13.17207261956732, 13.91981431878607, 13.095577523116825, 13.405988675235129, 13.144871284931902, 13.597874214619402, 12.731745772059295, 13.90083238519232])]
