An example of a static portlet (from GothCandy.com, Japanese removed):
class ProfilePortlet(Portlet):
title = "Profile"
template = """
<div xmlns:py="http://purl.org/kid/ns#"; class="portlet tags">
<h2>profile</h2>
<p class="profile"><strong>Name:</strong>Alice McGregor</p>
<p class="profile"><strong>Location:</strong>British
Columbia, CA</p>
<p class="profile quote">Growing up in a small town is
tough when you're this strange.</p>
<!-- ... -->
</div>
"""
An example of a slightly less static portlet, for the blog portion of
GothCandy.com:
class TagPortlet(Portlet):
title = "Tags"
template = """
<div xmlns:py="http://purl.org/kid/ns#"; class="portlet tags">
<h2>Tags</h2>

A list of active portlets is passed to each template call (I use a
registered global in tg.portlets, but they can be passed as
arguments, too). The template calls the portlets like this:
<div py:for="portlet in hasattr(self, 'portlets') and portlets or tg.portlets()" py:replace="portlet(self.__dict__)" />
self.__dict__ is passed to allow the portlet full access to all arguments passed to the template.
