title: Remove middle set of brackets inside numpy.ndarray
body: <p>I have a numpy.ndarray that looks like this:</p>
  <pre><code>[[['37.7602,-122.4703' '37.7602,-122.4703']
  ['37.7602,-122.4703' '37.7941,-122.4078']
  ['37.7602,-122.4703' '37.8156,-122.284']
  ['37.7602,-122.4703' '37.8163,-122.2467']
  ['37.7602,-122.4703' '37.7599,-122.4148']
  ['37.7602,-122.4703' '37.8268,-122.2526']]
  
  [['37.7941,-122.4078' '37.7602,-122.4703']
  ['37.7941,-122.4078' '37.7941,-122.4078']
  ['37.7941,-122.4078' '37.8156,-122.284']
  ['37.7941,-122.4078' '37.8163,-122.2467']
  ['37.7941,-122.4078' '37.7599,-122.4148']
  ['37.7941,-122.4078' '37.8268,-122.2526']]]
  </code></pre>
  <p>Is there an efficient way to remove the middle set of brackets so that it looks like this instead:</p>
  <pre><code>[['37.7602,-122.4703' '37.7602,-122.4703']
  ['37.7602,-122.4703' '37.7941,-122.4078']
  ['37.7602,-122.4703' '37.8156,-122.284']
  ['37.7602,-122.4703' '37.8163,-122.2467']
  ['37.7602,-122.4703' '37.7599,-122.4148']
  ['37.7602,-122.4703' '37.8268,-122.2526']
  ['37.7941,-122.4078' '37.7602,-122.4703']
  ['37.7941,-122.4078' '37.7941,-122.4078']
  ['37.7941,-122.4078' '37.8156,-122.284']
  ['37.7941,-122.4078' '37.8163,-122.2467']
  ['37.7941,-122.4078' '37.7599,-122.4148']
  ['37.7941,-122.4078' '37.8268,-122.2526']]

  <p>I imagine it can be done with looping, but I'm curious if there's a non-loop way to do this, since I want my implementation to scale easily.</p>
  <p>Thanks!</p>
