<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>&</code> operator.</p>
