In fact Ipython is so feature rich, some people even use it as 
login shell.

Short demo:
% ipython
Python 2.5.2 (r252:60911, Nov 14 2008, 19:46:32) 
Type "copyright", "credits" or "license" for more information.

IPython 0.8.4 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object'. ?object also works, ?? prints more.

control the behavior of IPython itself, plus a lot of system-type
features. All these functions are prefixed with a % character,
