Have you tried executing the code with and without the decorator?

$ python2 without-decorator.py
John Doe
$ python2 with-decorator.py
<p>John Doe</p>

Basically, the decorator wraps the output of your get_fullname
function with HTML <p> tags.

(Running code examples is a great way to understand them.)
