Python - Encapsulation and Data Protection

What is the issue with this code snippet?

class Bike:
    def __init__(self, speed):
        self._speed = speed

    @property
    def speed(self):
        return self._speed

    @speed.setter
    def speed(self, value):
        if value >= 0:
            self._speed = value

b = Bike(20)
b.speed = -5

AThe setter allows negative speed values which is invalid

BThe setter does not update the _speed attribute

CThe setter does not check for negative values properly

DThe getter method is missing

Step-by-Step Solution

Solution:

Step 1: Analyze setter condition
The setter only updates _speed if value >= 0, so negative values are ignored.
Step 2: Check what happens when b.speed = -5
Since -5 < 0, the setter does not update _speed, silently ignoring invalid input.
Step 3: Identify the problem
Setter should raise an error or handle invalid values explicitly; silently ignoring is a logical flaw.
Final Answer:
The setter does not check for negative values properly -> Option C
Quick Check:
Setter silently ignores invalid input [OK]

Quick Trick: Setter must handle invalid values explicitly [OK]

Common Mistakes:

Ignoring invalid setter inputs silently
Not raising exceptions for invalid values
Assuming setter always updates attribute
