I'd been looking forward to this particular lesson all semester, but when I got home and copied a sample program from my textbook verbatim, IDLE does nothing. No error, no nothing. Any ideas?

You need to define __init__, not _init_.  Python special methods are 
named with double underscore leading and trailing, and __x__ is 
pronounced "dunder-x".
