Quick Check: Python Multiple Inheritance and Method Resolution Order

Review

1. Which attribute lists only the classes named directly in a class definition's base list?

   __bases__ contains the direct base classes; __mro__ contains the complete method-resolution order.
2. If two direct bases define the same method and the first base appears before the second, what does that base order contribute?

   The local left-to-right base order contributes to the MRO and therefore to inherited method lookup.
3. In cooperative multiple inheritance, what does super() continue with?

   In a cooperative hierarchy, super() delegates to the next class in the MRO.
4. Why does a shared base appear only once in the MRO of a diamond hierarchy?

   C3 method resolution produces a consistent linear order in which a shared ancestor is not visited twice.
5. What happens when a multiple-inheritance hierarchy cannot satisfy its ordering constraints?

   Python raises TypeError when the requested bases cannot be arranged into a consistent MRO.
