how to convert list of string to one string
<p>I have list of values:</p>

<pre><code>    md5=['1111','3333','44444','555555','56632423','23423514','2342352323']
</code></pre>

<p>I want to concatenate them into a string:</p>

<pre><code>    md5=1111&amp;md5=3333&amp;md5=44444&amp;md5=555555&amp;md5=56632423&amp;md5=23423514&amp;md5=2342352323
</code></pre>

<p>What is the best way to do that?</p>
