Bad google day? Or just to lazy to do it? And what is "the book"? There are
quite a few out there, some about python the language, others about snakes
of the same name. Which one?

>>b.bar

>>b

<__main__.Foo object at 0x402ae68c>

There is also pickle.dumps and pickle.loads to work
directly with files. Further there is module cpickle
which offers the same functionality as pickle but which
is faster.
