Have a look at

http://www.zope.org/Members/htrd/howto/FunctionTemplate

Its a wrapper object for python functions that gives them *exactly*
the same calling convention as dtml methods. I developed this as a way
to replace overworked dtml without having to modify every other bit of
dtml that called it.

define your function as

def my_method(self,_):
    stuff goes in here

to invoke it from dtml use <dtml-var my_method>
