Most pythonic way to process this text file using python
<p>I have a text file containg test data that looks like:</p>

<pre><code>hdr 1

hdr2

hdr3

data1

data2

data3

data1

data2

....
</code></pre>

<p>There is a blank line between every line.</p>

<p>I need to create a list of lists containing</p>

<pre><code>[[hdr1,hdr2,hdr3],[data1,data2,data3],[data1,data2,...]
</code></pre>

<p>What would be a concise, pythonic way of doing this?</p>
