[Zope] python ignorance shining through...

[Tony McDonald]

Hi all,
I've got an external method that does an SQL lookup and retrieves 
(essentially) two fields, tagclass and content.
What I'm doing at the moment is;

if tagclass == 'modulecontributor':
   template_str = self.RENDER.modulecontributor.read_raw()
   template = DocumentTemplate.HTML(template_str)
   theresult = template(self, content=content)
   return theresult

How can I do something like;

try:
   template_str = self.RENDER.(the contents of tagclass).read_raw()
   template = DocumentTemplate.HTML(template_str)
   theresult = template(self, content=content)
   return theresult
except KeyError:
   return "no renderer for %s" % tagclass

any pointers gratefully received..
tone
