Can Python test the membership of multiple values in a list?
<p>I want to test if two or more values have membership on a list, but I'm getting an unexpected result:</p>

<pre><code>&gt;&gt;&gt; 'a','b' in ['b', 'a', 'foo', 'bar']
('a', True)
</code></pre>

<p>So, Can Python test the membership of multiple values at once in a list?
What does that result mean?</p>
