title: Accessing an array element in Python
body: <p>On running the following line in Python (vT is an array of floats):</p>
  
  <p>y = np.nonzero(vT &lt; flag)</p>
  
  <p>I get y as:</p>
  
  <p>(array([1939, 1940, 1941, ..., 9997, 9998, 9999], dtype=int64),)</p>
  
  <p>Question: How do I access the first element (i.e. 1939) from this result?</p>
