Singleton implementation problems

[Urizev]

Hi everyone

I have developed the singleton implementation. However I have found a
strange behaviour when using from different files. The code is
attached.

Executing main
new MySet object
No singleton instance
New singleton:
<__main__.Singleton instance at 0x2b98be474a70>
new MySet object
There is a singlenton instance
new Member
new MySet object
No singleton instance
New singleton:
<myset.Singleton instance at 0x2b98be474d88>
new Member
new MySet object
There is a singlenton instance
new Member
new MySet object
There is a singlenton instance

I do not know why, but it creates two instances of the singleton. Does
anybody know why?

Regards
