The key is the "page extends" directive in PSP.  Here's a simple example
where the servlet base class has a method that returns a list of "records",
then the PSP renders those records:

########### StupidPageBase.py
from WebKit.Page import Page
class StupidPageBase(Page):
	def records(self):
		return ['foo', 'bar', 'qux']
###########

########### StupidPage.psp
<%@ page extends="StupidPageBase" %>

<ul>
<%for record in self.records():%>
	<li><%=record%>
<%end%>
</ul>
###########

Just stick both files in the same directory, then access StupidPage.psp.
