Python permutation
<p>How would I accomplish the following in python:</p>

<pre><code>first = ['John', 'David', 'Sarah']
last = ['Smith', 'Jones']

combined = ['John Smith', 'John Jones', 'David Smith', 'David Jones', 'Sarah Smith', 'Sarah Jones']
</code></pre>

<p>Is there a method to combine all permutations?</p>
