AND in Python's slicing with modulus
<p>How can you fix the code?</p>

<p>I am trying to have <code>i % 3 == 1</code> and <code>i != 16</code> unsuccessfully by</p>

<pre><code>data = "8|9|8|9|8|9|8|9|9|8|9|8|9|8|9|8"
arra = map(int,data.split("|"))

arra = sum(arra[1::3 and != 16]) for i in range(0, len(arra), 16)]        
                       |
                       |---// Problem here
</code></pre>
