[Solved] Identify the error in this code snippet:import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) try: GPIO.setup(18, GPIO.OUT) GPIO.output(18, true) except: GPIO.cleanup() | Raspberry Pi

Raspberry Pi - GPIO Basics with Python

Identify the error in this code snippet:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
try:
    GPIO.setup(18, GPIO.OUT)
    GPIO.output(18, true)
except:
    GPIO.cleanup()

AGPIO.output() cannot be used with GPIO.OUT

BGPIO.setup() is missing a pin number

CNo import statement for GPIO

DGPIO.cleanup() should be in finally, not except

Step-by-Step Solution

Solution:

Step 1: Understand exception handling for cleanup
Cleanup should run always, not only on exceptions.
Step 2: Why finally is better than except here
finally block runs regardless of error, ensuring cleanup.
Final Answer:
GPIO.cleanup() should be in finally, not except -> Option D
Quick Check:
Use finally for guaranteed cleanup [OK]

Quick Trick: Put cleanup in finally, not just except [OK]
