Evaluating subset of a list using in operator
<p>I have following test code.</p>

<pre><code>a = ['a', 'b', 'c', 'd', 'e']
c = a * 3
b = a
</code></pre>

<p>but <code>b in c</code> returns False. b is a sub sequence of c and the list c contains b. So why is it returning false?</p>

<p>Thanks in advance.</p>
