&gt;&gt;&gt; a = [1, 2, 3]
&gt;&gt;&gt; b = a
&gt;&gt;&gt; b is a
True

<font color="black">The association of a variable with an object is called a <b>reference</b>. In this example, there are two references to the same

<br />
<a name="@default552"></a><br />

An object with more than one reference has more
than one name, so we say that the object is <b>aliased</b>.<br /
