title: How to check if a numpy array contain a list of numbers?
body: <p>I have a numpy array with another arrays inside and I want to know how I can check if all the values of another numpy array (Or list) are the same of the first one.</p>
  
  <pre><code>array1 = np.array([[11,3,4,6,7,8,9,1,2], [6,7,2,1,9,5,3,4,8]])
  array2 = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9])
  </code></pre>
  
  <p>I tried to do it with the <code>array2 in np.sort(array1)</code> but it return True.</p>
  
  <p>I want to obtain False in the first array of the array [11,3,4,6,7,8,9,1,2] because the number 5 is not in and True in the second one [1, 2, 3, 4, 5, 6, 7, 8, 9].
  Thanks for taking your time to read it and trying to help.</p>
