read text file (colon-separated words) and get a list of tuples
<p>I have a text file called words.txt of word &amp; description pairs separated by a colon, example:</p>

<pre><code>word1:description 1 bla bla bla
word2:description 2 blah blah
...
</code></pre>

<p>I want a structure like this one:</p>

<pre><code>[('word1', 'description 1 bla'), ('word2', 'description 2 blah')]
</code></pre>

<p>if you think another structure different than a list of tuples is better just tell me...I would love the solution by using list comprenhesion but I'm stucked.</p>
