One int for every python object [duplicate]

Answer 1

@Martjin Pieters has the right idea, but I would suggest going with itertools.count for this one:

class MyObject(object):
    ID = itertools.count()

    def __init__(self):
       self.id = MyObject.ID.next()

>>> MyObject().id
0
>>> MyObject().id
1
>>> MyObject().id
2
>>> MyObject.ID
count(3)

Hope this helps
