Python - Magic Methods and Operator Overloading

Identify the error in this class definition related to string representation methods:

class Dog:
    def __str__(self):
        return 'Dog'
    def __repr__(self):
        print('Dog object')

print(Dog())

A__repr__ should return a string, not print it

B__str__ method is missing self parameter

Cprint(Dog()) should be print(Dog)

D__repr__ method name is incorrect

Step-by-Step Solution

Solution:

Step 1: Check __repr__ method body
The __repr__ method uses print() instead of returning a string, which is incorrect.
Step 2: Understand consequences
Because __repr__ returns None, printing the object calls __str__ but repr() would fail to give a string.
Final Answer:
__repr__ should return a string, not print it -> Option A
Quick Check:
__repr__ must return string, not print [OK]

Quick Trick: Always return string in __repr__, never print [OK]
