[Solved] Identify the error in this Elevator class snippet: class Elevator: def __init__(self, current_floor): self.current_floor = current_floor def move_to(self, floor): current_floor = floor | LLD

LLD - Design — Elevator System

Identify the error in this Elevator class snippet:

class Elevator:
    def __init__(self, current_floor):
        self.current_floor = current_floor

    def move_to(self, floor):
        current_floor = floor

AIndentation error in move_to method

BMissing return statement in move_to method

CConstructor should not have parameters

DThe move_to method updates a local variable, not the elevator's floor

Step-by-Step Solution

Solution:

Step 1: Analyze move_to method
The method assigns current_floor = floor without self., so it changes a local variable only.
Step 2: Understand instance variable update
To update the elevator's floor, it should be self.current_floor = floor.
Final Answer:
The move_to method updates a local variable, not the elevator's floor -> Option D
Quick Check:
Missing self. means local variable used [OK]

Quick Trick: Use self. to update instance variables inside methods [OK]

Common Mistakes:

MISTAKES

Forgetting self. prefix
Thinking return is needed to update state
Assuming indentation is wrong without checking
