bpython doesn't attempt to create anything new or groundbreaking, it simply brings together a few neat ideas and focuses on practicality and usefulness. For this reason, the "Rewind" function should be taken with a pinch of salt, but personally I have found it to be very useful. I use bpython now whenever I would normally use the vanilla interpreter, e.g. for testing out solutions to people's problems on IRC, quickly testing a method of doing something without creating a temporary file, etc..

ghost.py is a webkit web client written in python.

But for the casually interested or schoolchildren with several activities competing for their attention, programming concepts like variables and loops and data types aren’t interesting in themselves.

"Jinja is a sandboxed template engine, written in Python of course. It's created by the guys over at Pocoo. It has a number of improvements over the Django engine, including faster rendering. Most of all, it allows you to place logic in templates where you need to, when Django does not."

"SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL."

"Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google's webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure."
