Python - Magic Methods and Operator Overloading

What will be the output of this code?

class Box:
    def __init__(self, volume):
        self.volume = volume
    def __lt__(self, other):
        return self.volume < other.volume

b1 = Box(10)
b2 = Box(20)
print(b1 < b2)

ANone

BTrue

CTypeError

DFalse

Step-by-Step Solution

Solution:

Step 1: Understand __lt__ method behavior
The __lt__ method compares the volume attributes of two Box objects using <.
Step 2: Evaluate comparison
b1.volume is 10 and b2.volume is 20, so 10 < 20 is True.
Final Answer:
True -> Option B
Quick Check:
__lt__ returns True if left volume is less [OK]

Quick Trick: __lt__ returns True if left is less than right [OK]

Common Mistakes:

Expecting False because 10 is less
Confusing __lt__ with __gt__
Thinking it raises an error
