Pretty basic multiple inheritance question.
Start with a clear 'yes' and immediately mention multiple inheritance. Then explain the method resolution order (MRO) and how Python uses C3 linearization to resolve conflicts. Finally, discuss practical trade-offs and alternatives like composition, showing you understand both the mechanics and design implications.
Pro tip: Mention that while multiple inheritance is powerful, it can lead to the diamond problem; showing awareness of when to avoid it (e.g., favoring composition) demonstrates senior-level judgment.
Confirm that Python supports multiple inheritance, allowing a subclass to inherit from multiple base classes.
Describe how Python resolves method and attribute lookup using the MRO, computed via the C3 linearization algorithm.
Discuss the diamond problem and how Python's MRO handles it, ensuring a consistent and predictable order.
Weigh the benefits (code reuse, mixins) against drawbacks (complexity, ambiguity) and mention alternatives like composition.
Give a simple code example or a real-world scenario (e.g., mixins) to illustrate multiple inheritance in practice.
