title: Why do I get an AttributeError when using .count() in python
body: <p><code>array1=[ 0  5  6  6  6  0  6  0  6  8  0 19 24  7  0  4  9 14 12  0 22 17  1  0 19 6 17  4  7  0 17 24  0  6  9 22]</code></p>
  
  <pre><code>i=0
  while i&lt;23
        m= array1.count(i)
        i=i+1
  </code></pre>
  
  <p><code>AttributeError: 'numpy.ndarray' object has no attribute 'count'</code></p>
  
  <p>Why does attribute error appear when i use .count()? do I need to import something?</p>
