what is the __dict__ object?

[wavic]

Perhaps this will give us some clue:

>>> class A:
...     pass
... 
>>> class B:
...     pass
... 
>>> for obj in (A.__dict__, B.__dict__):
...     print(type(obj))
... 
<class 'mappingproxy'>
<class 'mappingproxy'>

Now, the question is: what is mappingproxy?

Hm! Didn't get anything.
