Python string formatting
<p>I see you guys using</p>

<pre><code>url = '"%s"' % url # This part

&gt;&gt;&gt; url = "http://www.site.com/info.xx"
&gt;&gt;&gt; print url
http://www.site.com/info.xx
&gt;&gt;&gt; url = '"%s"' % url
&gt;&gt;&gt; print url
"http://www.site.com/info.xx"
</code></pre>

<p>Is it advanced Python? Is there a tutorial for it? How can I learn about it?</p>
