python for loop extending
<p>I wonder why the for loop is not extending it's iteration:</p>

<pre><code>    for link in frontLinks:  
        #try:           
        getCurlink = self.getHref(link) # get current site links
        #print getCurlink
        #print frontLinks 
        if getCurlink:
            frontLinks = frontLinks + getCurlink
</code></pre>

<p>This line:</p>

<pre><code>frontLinks = frontLinks + getCurlink
</code></pre>

<p>doesn't apply to frontLinks of the "for" loop. Any ideas??</p>
