Most pythonic way to truncate a list to N indices when you can't guarantee the list is at least N length?
<p>What is the most pythonic way to truncate a list to N indices when you can not guarantee the list is even N length?  Something like this:</p>

<pre><code>l = range(6)

if len(l) &gt; 4:
    l = l[:4]
</code></pre>

<p>I'm fairly new to python and am trying to learn to think pythonicly.  The reason I want to even truncate the list is because I'm going to enumerate on it with an expected length and I only care about the first 4 elements.</p>
