Hi, yet again to myself!
I've realised after further testing and reading that I actually need
to do this:
>>>dic_myinstances={}
>>>class MyClass(object):
def __new__(cls,id):
global dic_myinstances
if dic_myinstances.has_key(id):
return dic_myinstances[id]
else:
dic_myinstances[id] = super(MyClass, cls).__new__(cls, id)
return dic_myinstances[id]
def __init__(self,id):
print id
>>>ins1 = MyClass('xx')
'xx'
>>>ins2 = MyClass('yy')
'yy'
>>>ins3 = MyClass('xx')
'xx'
>>>ins3 is ins1
True
