Bottle is a fast, simple and lightweight WSGI micro web-framework for Python. It is similar to Flask, but it is even more lightweight and minimal. In fact, the whole framework is contained in a single 44kb file (as of version 0.9.6). If you don't need many of the built-in functions in Flask or any bigger Python web framework, I personally recommend to use Bottle. Now, I am using it to build a simple static website in Google App Engine. Bottle is pluggable to other modules if there's a need to add other goodies.
