Python - Multiple Inheritance and Method Resolution

What will be the output of the following code?

class Parent1:
    def message(self):
        return "Message from Parent1"

class Parent2:
    def message(self):
        return "Message from Parent2"

class Child(Parent2, Parent1):
    pass

obj = Child()
print(obj.message())

AMessage from Parent2

BMessage from Parent1

CError: Ambiguous method call

DNone

Step-by-Step Solution

Solution:

Step 1: Understand inheritance order
The class Child inherits from Parent2 first, then Parent1.
Step 2: Method Resolution Order (MRO)
Python looks for the message method in Child, then Parent2, then Parent1.
Final Answer:
Message from Parent2 -> Option A
Quick Check:
Check inheritance order and method lookup [OK]

Quick Trick: MRO follows left-to-right inheritance order [OK]

Common Mistakes:

Assuming Parent1's method is called first
Thinking Python raises ambiguity error
Ignoring the order of base classes
