Yep, that&#x27;s right. To lay out the example the way you did in the article, it would look like:<p><pre><code>    &gt;&gt;&gt; foo = A.b
    &gt;&gt;&gt; bar = A.b
    &gt;&gt;&gt; hex(id(foo))
    &#x27;0xdeadbeef&#x27;
    &gt;&gt;&gt; hex(id(bar))
    &#x27;0xdecafcab&#x27;
    &gt;&gt;&gt; foo is bar
    False</code></pre>
