trying to teach myself python, stuck during one chapter of this book, very simple question
<pre><code>from sys import argv

script, user_name=argv
</code></pre>

<p>that's part of the program i'm trying to run and I don't think any more is necessary. I try and run it by typing into terminal:</p>

<pre><code>python exl.py script user_name
</code></pre>

<p>That should work, right? I know this is pretty simple, but I am really stuck. Also I don't completely understand what I'm doing there. The book I'm using is dealing with paramaters and unpacking right now and I don't completely get it. An explanation would be awesome. </p>

<p>Thanks </p>
