<li>Method of <a href="../">Expression</a></li>
</ul>
<p>This evaluates to true if both the expression on the left as well as the
expression on the right are true. This is one of the few operators that
differs between Python and templates. In templates you have to use the
<code>and</code> method whereas in Python have to use the <code>&amp;</code> operator.</p>
