[Zope] returning values from python scripts

I'm not sure how to get at the return values of python scripts from dtml. Assume I have the following python script called 'test': foo = "john doe" bar = 42 return foo,bar How can I get at the returned value? <dtml-var test> returns both elements. I was hoping to be able to do something like <dtml-var test.foo> or <dtml-var test[0]>
