Of course Python can be even more confusing so that for example

 >>> class NeverEqual(int):
... 	def __new__(cls,v):
... 		self = int.__new__(cls,v)
... 		return self
... 	def __eq__(self,other):
... 		return False
...
 >>> a=NeverEqual(1)
 >>> a
1
 >>> a==1
False
 >>> a==a
False
 >>> not (a != a)
True
 >>> a!=a
False
 >>>

so I think that assignment doesn't always make things equal even chronologically.
