Why would you > need another database abstraction on top of that? A first point is that the DB-API doesn't hide the differences between various SQL dialects. A second point is that DB-API requires you to embed SQL statements as strings, while SQLAlchemy allow you to build your SQL queries in pure Python. (and FWIW, if using an existing DB, you don't even have to describe the schema a second time to use it). Well, just start playing with it, and I really doubt you'll want to come back to the embedded hand-written SQL !-) My 2 cents -- http://mail.python.org/mailman/listinfo/python-list
