I've ported Outlet to Python (naming it pyLet) and wanted to share with the Outlet community:
https://sourceforge.net/projects/pylet/
My motivation was that of all the ORM's I've tried for various languages, Outlet strikes the best balance between power on the one hand, and simplicity and lightweight-ness (sic.).
The interface to pyLet is pretty much the same as it is for Outlet, except that where Outlet uses associative arrays in configuration, pyLet uses dictionaries. Where Outlet uses non-associative arrays, pyLet uses lists.
The project is based on DB API, but has only been tested the the MySQLdb driver.
The project has yet to be extensively tested, but I'm currently using pyLet in a major project I'm working on, so it'll get a good workout in the course of that project.
Anyways, hopefully others will find this useful!
