Alternatively your external method can return objects to the calling DTML.
for an external method spammethod you could do omething like:

class A:
	pass


def spammethod(self,n):
	a=[]
	for i in range(n):
		tmp=A()
		tmp.no=i
		a.append(tmp)
	return a

Then in your DTML you can do something like

<!--# in "spammethod(20)" sort=no -->
<!--# var no -->
<!--#/in-->
