Raspberry Pi - GPIO Basics with Python

Examine this code snippet:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
try:
    GPIO.setup(17, GPIO.OUT)
    GPIO.output(17, true)
finally:
    pass

What is the issue preventing proper GPIO cleanup?

AThe <code>finally</code> block does not call <code>GPIO.cleanup()</code>

BThe <code>GPIO.output</code> uses lowercase <code>true</code> instead of <code>True</code>

CThe GPIO mode is set incorrectly

DThe <code>try</code> block is missing an <code>except</code> clause

Step-by-Step Solution

Solution:

Step 1: Check cleanup call
The finally block is empty and does not call GPIO.cleanup().
Step 2: Identify impact
Without calling cleanup, GPIO pins remain configured, causing issues.
Step 3: Note other errors
While true should be True, the main issue is missing cleanup.
Final Answer:
The finally block does not call GPIO.cleanup() -> Option A
Quick Check:
Cleanup must be explicitly called [OK]

Quick Trick: Always call GPIO.cleanup() in finally [OK]
