How do you create an incremental ID in a Python Class

I would like to create a unique ID for each object I created - here's the class:

class resource_cl :
    def __init__(self, Name, Position, Type, Active):
        self.Name = Name
        self.Position = Position
        self.Type = Type
        self.Active = Active

I would like to have a self.ID that auto increments everytime I create a new reference to the class, such as:

resources = []
resources.append(resource_cl('Sam Sneed', 'Programmer', 'full time', True))

I know I can reference resource_cl, but I'm not sure how to proceed from there...

Concise and elegant:

import itertools

class resource_cl():
    newid = itertools.count().next
    def __init__(self):
        self.id = resource_cl.newid()
        ...
