unpacking a tuple with print
<p>the second unpacking is not working with print, what is the reason?</p>

<pre><code>for a in stok.iteritems():
...  c, b = a
...  print c, b
</code></pre>

<p>this one is valid</p>

<p>but this one is not</p>

<pre><code>for a in stok.iteritems():
...  print c, b = a
</code></pre>
