Quick Check: Python Exception Groups and except*

Review

1. What problem does ExceptionGroup solve?

   ExceptionGroup carries multiple independent exceptions together so they can be handled as a group.
2. What does an except* ValueError handler receive from an ExceptionGroup containing ValueError and TypeError instances?

   The handler receives the subgroup whose contained exceptions match ValueError.
3. Can more than one except* handler execute for one ExceptionGroup?

   Several except* clauses can each execute once for their matching subgroup of the group.
4. What happens to exceptions in an ExceptionGroup that no except* clause matches?

   The unmatched portion of the group is propagated and can be handled by an outer handler.
5. Which statement is not allowed inside an except* clause?

   return, break, and continue are prohibited in except* clauses.
