So, in a higher level class, have a weakref list which contains a
reference to each person. Total count will be len(list) at any time.
Now, I couldnt find a weakref list - so I am using WeakKeyDictionary
with the value as None - since len(dict) also should give me the data
I typically use a WeakValueDictionary, with the key id(obj).
...
Now, the only two operations that I am doing are ->
__init__:
d = weakref.WeakKeyDictionary()
method y:
x = aa()
d[x] = None
method z:
total = len(d)
At least at one point, the WeakValueDictionary was more stable. I don't
remember the details, but I remember my work-around. If you do have
troubles, try using almost the same code you now use, but substitute for
the obvious lines above:
d = weakref.WeakValueDictionary()
and
d[id(x)] = x
