I know there are a ton of Python frameworks out there. Can you guys point me in the right direction? My primary concern is simplicity, I don't need a lot of extraneous features. Here are a couple of other things that I'd want (or don't want):
web2py is 265Kbytes of source code and 1.2MB all inclusive (compare with 4.6MB of Django). Yet web2py will do everything you need (manage session, cookies, request, response, cache, internationalization, errors/tickets, database abstraction for GAE, SQLite, MSSQL, MySQL, Postgres, Oracle, FireBird, etc.) It does not need installation - just unzip and click on it - and you can do development in your browser.
Web2py has both routes and reverse routes.
Web2py has a hierarchical template systems which means a view can extend a layout which can extend another layout, etc. views can also include other views.
