Python - Constructors and Object Initialization

What will be the output of this code?

class Car:
    def __init__(self, brand='Toyota', year=2020):
        self.brand = brand
        self.year = year

car1 = Car()
print(car1.brand, car1.year)

AToyota 2020

BToyota None

CNone 2020

DError: Missing arguments

Step-by-Step Solution

Solution:

Step 1: Check constructor default values
brand defaults to 'Toyota', year defaults to 2020 if no arguments are passed.
Step 2: Object creation and attribute values
car1 is created without arguments, so brand='Toyota' and year=2020 are assigned.
Final Answer:
Toyota 2020 -> Option A
Quick Check:
Defaults used when no args passed = Toyota 2020 [OK]

Quick Trick: No args means defaults are assigned automatically [OK]

Common Mistakes:

MISTAKES

Expecting error without arguments
Assuming attributes become None
Confusing default values
