How to add custom parameters to an URL query string with Python?
<p>I need to add custom parameters to an URL query string using Python</p>

<p>Example:
This is the URL that the browser is fetching (GET):</p>

<pre><code>/scr.cgi?q=1&amp;ln=0
</code></pre>

<p>then some python commands are executed, and as a result I need to set following URL in the browser:</p>

<pre><code>/scr.cgi?q=1&amp;ln=0&amp;SOMESTRING=1
</code></pre>

<p>Is there some standard approach?</p>
