Python object, where is `__name__` stored?

Question

I am confused as to where __name__ is stored within a Python object.

For example, take Python str:

In [1]: hasattr(str, "__name__")
Out[1]: True

In [2]: getattr(str, "__name__")
Out[2]: 'str'

In [3]: "__name__" in str.__dict__
Out[3]: False

In [4]: "__name__" in list(dir(str))
Out[4]: False

You can see from [1] + [2] that str.__name__, that it has the value "str". However, I can't find where it's stored by using dir() and __dict__.

I know I am missing something, but from all my reading I can't figure it out. Can you please help me?

Places Looked

From these questions:

1. python __getattr__ and __name__
2. Why do python instances have no __name__ attribute?
   • Thank you to everyone for pointing #2 out

In [5]: str.__class__.__name__
Out[5]: 'type'

In [6]: "hi".__class__.__name__
Out[6]: 'str'

One can see a str instance has __name__ = "str" stored within __class__.

Where is __name__ = "str" within the class str?

Thanks in advance for the help!

Later Edit

Turns out this was a duplicate. The answer (as stated in the comments) is:

In [1]: type.__dict__['__name__'].__get__(str)
Out[1]: 'str'

And the reasoning can be found in these questions:

• Setting a class __name__ declaratively
• Why is n.__name__ an attribute error when type(n).__name__ works?
