I suggest returning a dict containing the IP address, to make it easier to add additional state later if needed. That said, I wouldn't pickle a TCP client in the first place. You may be able to restore the client state, but you can't easily restore any server state, which could easily lead to mismatching network states. Also, what do you think should happen if the connection fails while unpickling? > Similarly, whilst unpickling, __setstate__ will be called in a manner > similar to this: > x.__setstate__(self, unpickledIP) > > __setstate__ can then populate 'x' by doing > self.x = str(unpickledIP) > > the type info is not lost during pickling is it, therefore 'str' is not > required is it?
