Looping through a list of tuples in Scala
<p>I have a sample <code>List</code> as below</p>

<pre><code>List[(String, Object)]
</code></pre>

<p>How can I loop through this list using <code>for</code>?</p>

<p>I want to do something like </p>

<pre><code>for(str &lt;- strlist)
</code></pre>

<p>but for the 2d list above. What would be placeholder for <code>str</code>?</p>
