title: Remove redundant square brackets in a list python
body: <p>I am working with a list of lists longitudes and latitudes. Each inner list has an extra pair or square brackets.</p>
  <p>For instance:</p>
  <pre><code>[[-87.77621462941525,-87.77676645562643,-87.77906119123564]]
  </code></pre>
  <p>I would like to remove the extra brackets and be left with:</p>
  <pre><code> [-87.77621462941525,-87.77676645562643,-87.77906119123564] 
  </code></pre>
  <p>Thanks</p>
