python cpu consumption
<p>I wrote a simple python program that looks to me like it should be cpu intensive:</p>

<pre><code>for a in range(0,1500):
      for b in range (0,a):
            for c in range(0,b):
                   x = a+b+c
                   print x
</code></pre>

<p>What happens is that it takes a really long time on solving it, but cpu consumption stays at around 25%. Why does this happens insead of using more cpu for a shorter time?</p>
