[Zope] batching in python scripts?

Is there any way to use the dtml batch processing and associated variables (sequence-start, etc.) from within a python script? Or do I have to program it myself? I like the DTML batch processing functionality because it is comprehensive and easy to use, but unfortunately I need to use python scripts.
