I was reading up on function attributes. Incredible new feature... You can
now add member functions to classes and class instances without having to
inherit from them. Can be done at runtime!
Look what you can do with them
------picklesocket.py------
from cPickle import loads, dumps, UnpickleError
def unpickle(maxbytes):
data = self.sock.recv(maxbytes)
return dumps(data)
def pickle(anything):
"""anything can be a list, dictionary, tuple, string.. you name it
"""
data = loads(anything)
self.sock.send(data)
def patchSocket(instance):
pickle.sock = unpickle.sock = instance
instance.pickle = pickle
instance.unpickle = unpickle
sock = socket(...)
patchSocket(sock) # adds new member methods : pickle and unpickle
