Noob: Python DocBook to PDF

Hello ... genuine newbie trying to get his brain around DocBook.

I'm writing an application in Python that needs to produce reports and 
printouts. DocBook seems like a great starting point for defining the 
layouts.

For better or worse, PDF seems like the way to send printouts to the 
printer. Are there any other options (when starting from DocBook)?

Using Python, how do I get from my DocBook XML XSLT files to PDF?

Thanks,
