module for working with the result set

[john fabiani]

Hi,
newbie question:
PyPgSQL (postgres driver) returns a list (not a tuple O'Rielly states 
DBAPI returns a tuple) and most of the books describe how to work with 
tuples and dictionaries when working with a result set. Does anyone know 
of a paper or tutorial that explains a few ways to deal with result 
sets. Or if anyone knows of a module that will help (that I can study) - 
that would be just as helpful?

TIA
John
