How to deal __getattr__

[limodou]

I resolved the problem via defining __eq__method, just like:

>>> class A:
	def __getattr__(self, name):
		print name
		return None
	def __eq__(self, obj):
		return id(self) == id(obj)

	
>>> a=A()
>>> b=A()
>>> a==b
False

I don't know whether it's the right solution, any ideas?
