The current description is "The name BaseClassName must be defined in a scope containing the derived class definition", which did not conform to the actual situation ,e.g. the base class object is not in the same scope as the derived class. |

Hi. Can you please provide a small code snippet illustrating where this diverges from the actual behaviour? |

Code:
>class A(object):
pass
'object' is not in the same scope as 'A'

It is part of the global scope, which contains all other scopes. (I'm not 100% sure I'm comfortable with that language, but it doesn't seem obviously wrong.) |

The previous description about scope classify it into 3 types explicitly, which means the scope containing the current module's global names is not same as the scope containing built-in names. |

IMO there's no actual bug in Python. Perhaps documentation can be clarified in a short simple way. I would reiterate the point that restating facts of the language all over the documentation is not a great idea, but maybe here the benefits outweigh the drawbacks. Anyway I think the bug is clear now (it's a docs issue if anything) so I'd leave it open until someone offers a patch or a strong argument why it shouldn't be clarified.

Would it make it clearer if we said "BaseClassName must be defined in a namespace accessible from the scope containing the dervied class definition" ? |

Worth putting them side by side I think: "The name BaseClassName must be defined in a scope containing the derived class definition" vs. "BaseClassName must be defined in a namespace accessible from the scope containing the derived class definition" |

As for me, i prefer the new description, which is clear and easy to understand. |
