[Solved] Find the error in this code: class Car: def __init__(self, model): model = model car = Car("Tesla") print(car.model) | Python

Python - Classes and Object Lifecycle

Find the error in this code:

class Car:
    def __init__(self, model):
        model = model

car = Car("Tesla")
print(car.model)

AAttributeError because model is not set as instance attribute

BSyntaxError due to missing self

CTypeError because __init__ has wrong parameters

DNo error, prints Tesla

Step-by-Step Solution

Solution:

Step 1: Check attribute assignment in __init__
The code assigns model = model, which only assigns local variable, not instance attribute.
Step 2: Accessing car.model causes error
Since self.model is never set, car.model does not exist, causing AttributeError.
Final Answer:
AttributeError because model is not set as instance attribute -> Option A
Quick Check:
Use self.model = model to set instance attribute [OK]

Quick Trick: Always use self.attribute = value to set instance attributes [OK]
