Re: Help with regular expression in python
You don't seem to account for the whitespace between the floats. Try
> '([-+]?(\d+(\.\d*)?|\.\d+)([eE][-+]?\d+)?\s+){32}'
(just added \s+).

Re: Strange location for a comma
In this case those are not tuples but rather arguments in a function
call. The extra comma does not change the evaluation, my guess is that
it is there for easier adding/removing arguments without having to care
about trailing commas.

Re: Python as a replacement to PL/SQL
PostgreSQL supports PL/SQL, PL/TCL, PL/Python, PL/Perl and I've also seen PL/Java add on module.

Re: Convert DDL to ORM
Hi, for the project I'm working on right now I've written a simple "SQL create script to ORM generator". I use SQLalchemy as well and this generator takes all tables and prepares classes, maps them to tables, introspects them and creates explicit attribute definitions in the classes. Contact me off-list for more details.
