Python - Magic Methods and Operator Overloading

Identify the issue in this code snippet:

class Animal:
    def __init__(self, species):
        self.species = species
    def __repr__(self):
        return species

pet = Animal('Dog')
print(pet)

A__init__ method is missing the self parameter

BThe __repr__ method should return self.species, not species

CThe class name should be lowercase

Dprint(pet) cannot be used with __repr__ method

Step-by-Step Solution

Solution:

Step 1: Check __repr__ method
The method tries to return 'species' which is undefined in its scope.
Step 2: Use instance attribute
It should return self.species to access the instance variable.
Final Answer:
The __repr__ method should return self.species, not species -> Option B
Quick Check:
Use self to access instance variables [OK]

Quick Trick: Always use self to access instance attributes [OK]

Common Mistakes:

Returning variable without self prefix inside methods
Misunderstanding __repr__ purpose
Ignoring scope of variables inside methods
