Attribute Access

Python follows more or less the following steps when looking up an attribute inside of an object:

• First looks at obj.__dict__[attribute]. If it is not found,
• Then looks at type(obj).__dict__[attribute]. If it is not found,
• Check __dict__ of all the superclasses.

However, if Pythons see that the attribute is implemented using a descriptor, it uses the descriptor methods (__get__).
