Q14: What is C3 Linearization and how does it calculate Method Resolution Order (MRO)?
Python uses the C3 Linearization Algorithm to compute a deterministic MRO for class hierarchies with multiple inheritance. It guarantees:
- Subclasses appear before parents.
- Parent classes maintain list order declared in class headers.
- Preserves local precedence order across complex diamond inheritance graphs.
Key Takeaways
- Algorithm powering Python's Method Resolution Order (MRO).
- Prevents diamond inheritance ambiguity errors.
