title: Why it shows different results while I use id() comment for numpy element?
body: <p>I'm a newbie for python. I used this below code to make array, and I checked the memory location.
  It showed different results. I don't know why. I thought both would show same results. Do you know why? If so please, let me know the reason. thanks in advance.</p>
  <pre><code>a = np.array([[0,1,2],[3,4,5],[6,7,8]]) 
  id(a[0][0]) #1301373082608
  id(a[0][0]) #1301373082704
  </code></pre>
