[Zope] Equivalent of dtml-with in script or ZPT?

[Steve McMahon]

Is there a way to achieve in a Python script an effect equivalent to

<dtml-with an_object>
   operations in context of an_object
</dtml-with>

? I know it's possible to call the object's methods, but if I need to 
pass the methods a context (for example to render a DTML method), I get 
the context of the object calling the script, not the context of an_object.

And, for that matter, is there a way to achieve the same effect in a 
TALES expression?

Thanks for all feedback!
