<p>Let's say I have the following list of tuples:</p>

<pre><code>[(1,2), (1,3), (1,4), (1,5), (1,6)]
</code></pre>

<p>I am trying to convert it to a simple list like I have below:</p>

<pre><code>[1,2,1,3,1,4,1,5,1,6]
</code></pre>

<p>How do I convert it to a simple list like the one above without having to iterate through each element and add the items one by one to another list?</p>

<p>Are there any fast and efficient ways to do this without actually iterating through the original list of tuples, or is there some built-in function/method to do this?</p>
