Python: converting tuple into 2D array
<p>I want to convert tuple like</p>

<pre><code>t = [(4,10),(9,7),(11,2),(2,2)]
</code></pre>

<p>into 2D array like:</p>

<pre><code>a = [[4,10],[9,7],[11,2],[2,2]]
</code></pre>

<p>I tried</p>

<pre><code>a = []
for i in t:  
    a.append(np.asarray(i))
print a
</code></pre>

<p>is there any easier way?</p>
