bpython - A fancy curses interface to the Python interactive interpreter

bpython is a lightweight Python interpreter that adds several features common to IDEs. These features include syntax highlighting, expected parameter list, auto-indentation, and autocompletion. (See below for example usage).bpython does not aim to be a complete IDE - the focus is on implementing a few ideas in a practical, useful, and lightweight manner.

bpython is a great replacement to any occasion where you would normally use the vanilla Python interpreter - testing out solutions to people's problems on IRC, quickly testing a method of doing something without creating a temporary file, etc..
