Python - Inheritance and Code Reuse

Which statement about method resolution order (MRO) in Python inheritance is true?

APython only uses the parent class methods, ignoring child methods.

BPython looks for methods in the child class first, then parent classes in order.

CPython randomly chooses which class method to use when multiple exist.

DPython requires explicit method calls to parent methods; otherwise, child methods are ignored.

Step-by-Step Solution

Solution:

Step 1: Understand MRO basics
Python searches for methods starting from the child class, then moves up the inheritance chain.
Step 2: Evaluate options
Python looks for methods in the child class first, then parent classes in order. correctly describes this search order.
Final Answer:
Python looks for methods in the child class first, then parent classes in order. -> Option B
Quick Check:
MRO = child first, then parents [OK]

Quick Trick: Python checks child methods before parent methods [OK]
