Is there a way to save the state of a class??

[EdwardT]

I just came across of a featuer that provides that saves objects into bytes
stream and stored as a file. The funciton is pickle, cPickle, marshal or
shelf. But I am not quite sure if they helps here and didn't find many
exmaple for explanation of their use.
Form the doc it says pickle and cPickle, as opposed to marshal, can be used
for user defines class also., while cPickle is just the faster form.


Can someone shed some light over this?
Thanks
