Bottle is a fast and simple WSGI-framework for the Python Programming Language. It offers request dispatching with url parameter support (routes), templates, key/value databases, a build-in HTTP server and adapters for many third party WSGI/HTTP-server and template engines. All in a single file and with no dependencies other than the Python standard library.
