title: How slicing and ellipsis works in numpy?
body: <p>I have been reading a very old documentation of <strong>Numpy</strong> and found out a weird notation which eludes my understanding. The documentation says <code>a[i:...]</code> is a shortcut for <code>a[i,:,:,:]</code>. </p>
  
  <p>The documentation being old is very vague and I would welcome any comments. </p>
  
  <p>Thanks,
  Prerit</p>
