You can run a dir() in the GUI IDLE or the command line IDLE and see
what's currently "cached", so to speak. In the GUI IDLE, you can
"flush" it out by going to the Shell menu and choosing Restart Shell.
It should only display the following after a restart:
>>> dir()
['__builtins__', '__doc__', '__name__']
