Resolved: Python strange namespace bahavior for class factory

Question:

I tried to write simple class factory using the “type” method. I called myclass_factory twice and It returned identical namespaces (case1 and case2). But the values of myclass attribute in that namespaces were different (!). Actualy it just what I need but I can not undestnad why I got that result. For my udestanding, since case1 and case2 are not objects but just same namespace (<class ‘main.MyClass’>) they should refer to the same memory and should be case1.myclass = case2.myclass
Please explain how It could be so?

>>> def myclass_factory(myclass):
...     return type('MyClass',(object,),{'myclass': myclass})
...
>>> class class1:
...     pass
...
>>> class class2:
...     pass
...
>>> case1 = myclass_factory(class1)
>>> case2 = myclass_factory(class2)
>>>
>>> case1
<class '__main__.MyClass'>
>>> case2
<class '__main__.MyClass'>
>>>
>>> case1.myclass
<class '__main__.class1'>
>>> case2.myclass
<class '__main__.class2'>
>>>
>>>

Answer:

Actually case 1 and case 2 are objects since you instantiate them. They are type objects and thus ordinary python objects. So you create two different type objects.
