Description

create_exception allows taking a base, which the new exception subclasses from.

Is there some way to create a new exception which uses multiple inheritance from two parents?

Research direction

Start with the create_exception API and its documentation at the linked docs.rs entry. Investigate how the base parameter is handled and whether PyO3 exposes a path for multiple Python exception parents. Done would require a defined, reviewed API approach rather than only confirming current behavior.
