that's not really much of an excuse for not reading *any* Python tutorial before
you jump in...

several people have already told you how to deal with this in Python. please see
the followups to your earlier post.

Ruby's DB interface, perhaps. Python's standard DB-API doesn't support this
by default, for portability and performance reasons. that doesn't mean that Python
don't have "hashes", just that the DB-API doesn't provide dictionary-style access
see the followups to your earlier post for more details, and ways to handle this.
(a much better way to deal with this is of course to *name* the variables in your
select statements, so 1) the database engine can spot errors early on, and 2) it
won't have to fetch data that you don't really need).
