Hi, I solved it myself! I realised that __new__ creates self prior to init, so this works:
>>>dic_myinstances={}
>>>class MyClass(object):
def __new__(self,id):
global dic_myinstances
if dic_myinstances.has_key(id):
return dic_myinstances[id]
else:
dic_myinstances[id] = self
return self
>>>ins1 = MyClass('xx')
>>>ins2 = MyClass('yy')
>>>ins3 = MyClass('xx')
>>>print ins3 is ins1
True
Is this the best way to do this?
