Bernie Day 01/25/05 I was using deepcopy on DeviceManager and this worked well. When I defined __deepcopy__, so I could have a handle to the children of the Master device Manager I got into trouble. I see that there is a method using a dic to limit this, but I can't seem to get it to work. This is not the code I was using but should represent it well. Thanks! ''' class DeviceManager: def __init__(self,devFile): DevFile = open(devFile) devList = [Device(line) for line in DevFile] #etc, etc... def __deepcopy__(self): miniMe = copy.deepcopy(self) miniMe.devList = tuple(devList) return miniMe class Device: def __init__(self,line): self.copyies = [] #do something with line here def __deepcopy__(self): miniMe = copy.deepcopy(self) self.copyies.append(miniMe) return miniMe DevMan1 = DeviceManager(devfile) devMan2 = copy.deepcopy(DevMan1) -- http://mail.python.org/mailman/listinfo/python-list
