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?

>>class Foo(object):

.... def __init__(self):
.... self.bar = 1
....

>>import pickle
a = Foo()
pickle.dumps(a)

"ccopy_reg\n_reconstructor\np0\n(c__main__\nFoo\np 1\nc__builtin__\nobject\np2\nNtp3\nRp4\n(dp5\nS'ba r'\np6\nI1\nsb."

>>b = pickle.loads("ccopy_reg\n_reconstructor\np0\n(c__m ain__\nFoo\np1\nc__builtin__\nobject\np2\nNtp3\nRp 4\n(dp5\nS'bar'\np6\nI1\nsb.")
b.bar

1

>>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.
