Really, the title says it all. Is there any way to compile all the instances of a class into a list, or other such data structure?
Finding all instances of a class?

BearofNH 104 I have done this on occasion. The easiest way to do this is have your __init__() routine append self to a list. If it's not "your" class I suppose you could override the __init__ method of the class.
Fortunately I never had to worry about deletes...

Gribouillis 1,391 Probably delete could be addressed by using WeakRefs...
Indeed, you can store the instances in a weakref.WeakValueDictionary for example
from weakref import WeakValueDictionary
class A(object):
instances = WeakValueDictionary()
def __init__(self):
self.instances[id(self)] = selfInstances disappear magically from the dictionary when their reference counts falls to 0.
Note that it's better to start a new thread than reviving an old one. The OP probably solved this problem a long time ago.
