Counting instances of a class?

Question

I\'ve been cleaning up some code from a module I\'m extending and I can\'t seem to find a way to Pythonify this code:

global_next_id = 1

class Obj:
  def __         


        

Answer 1

Try something like this:

from itertools import count

class Obj(object):
  _ids = count(0)

  def __init__(self):
    self.id = next(self._ids)
