Hi,
There was a mistake above, and then I'll explain what we're doing:
>>> insCacheClass = CacheClass(oref)
>>> insCacheProperty = CacheProperty(insOref,'Chapter')
should have been
>>> insCacheClass = CacheClass(oref)
>>> insCacheProperty = CacheProperty(insCacheClass ,'Chapter')
Now, to answer

Then don't do that.
Python allows any name to be reassigned to any value, with the
attitude of "we're
Thanks for your input. Here is my next version, which works very well,
but for one problem I explain below:
class CacheProperty(object):
def __init__(self, insCacheClass, name):
self.Name = name
self._bind_to_parent(insCacheClass)
self.__parent = insCacheClass

What it means is that references to "self.__data" (note the TWO leading

I don't understand this
Hi Ben,
Could I also do something like the following? What does it mean to
store the parent class as a private variable in the child class?
class CacheProperty(object):
def __init__(self, obj, parent, properties=None):
self.__data = obj
self._parent = parent

I presume
Hi,
I am having trouble designing my classes.
I have two classes. The first one wraps around an old-style class
called oref
Class CacheClass(object):
def __init__(self, obj):
self.__data = obj
def __getattr__(self, attr):
return getattr(self.__data, attr)
