I think you want
  name = listbox.get(listbox.curselection()[0])
  obj = getattr(Tkinter, name)
  description.config( text=obj.__doc__ )

A couple more tips:
- Don't use 'list' as the name of a variable, that name is already used 
as the type of the built-in list.
- Please respond to the existing thread rather than starting a new 
thread for each email, it makes it easier to follow the discussion.
