Why does Python use the C3 linearization algorithm for MRO in multiple inheritance?

hard🧠 Conceptual Q10 of Q15
Python - Multiple Inheritance and Method Resolution
Why does Python use the C3 linearization algorithm for MRO in multiple inheritance?
ATo allow methods to be called in random order
BTo speed up method calls by caching results
CTo ensure a consistent and monotonic method lookup order
DTo prevent inheritance from more than two classes
Step-by-Step Solution
Solution:

  1. Step 1: Understand C3 linearization purpose

    C3 linearization ensures a consistent, predictable order for method lookup in complex inheritance.

  2. Step 2: Eliminate incorrect options

    It does not speed up calls, allow random order, or limit number of base classes.

  3. Final Answer:

    To ensure a consistent and monotonic method lookup order -> Option C

  4. Quick Check:

    C3 linearization = consistent MRO [OK]
Quick Trick: C3 linearization keeps method order consistent and predictable [OK]
Common Mistakes:
MISTAKES
  • Thinking it speeds up calls
  • Believing it limits inheritance count
