Either the book is wrong or you have misinterpreted what you read.
 From http://docs.python.org/lib/module-sys.html:

excepthook(type, value, traceback)

This function prints out a given traceback and exception to sys.stderr.

When an exception is raised and uncaught, the interpreter calls  
sys.excepthook with three arguments, the exception class, exception  
instance, and a traceback object. In an interactive session this happens  
just before control is returned to the prompt; in a Python program this  
happens just before the program exits. The handling of such top-level  
exceptions can be customized by assigning another three-argument function  
to sys.excepthook.
