PyObject_GetAttr() can set not only AttributeError. If it sets a different error, it should not be overridden by AttributeError.
I suggest to use PyObject_GetOptionalAttr().

Why not chain the original error to a new exception (raise from)?

Or maybe this is a use case for adding a note to the original exception and letting it propagate on (if we don't want to change the type of the exception being raised).

Thank you for the reviews! |

I fixed some errors, please resolve conflicts. |

Would be great to mention this nice quality-of-life improvement with an example in What's New, similar to: https://docs.python.org/3/whatsnew/3.12.html#improved-error-messages |
