What will be the output of this code snippet?

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(7, GPIO.OUT)
print(GPIO.gpio_function(7))

Assuming pin 7 is set as output.

A0

B3

C2

D1

Step-by-Step Solution

Solution:

Step 1: Understand GPIO.gpio_function()
This function returns a number representing the pin's current function. For output pins, it returns 1.
Step 2: Check pin setup
Pin 7 is set as GPIO.OUT, so gpio_function(7) returns 1.
Final Answer:
1 -> Option D
Quick Check:
Output pin function code = 1 [OK]

Quick Trick: Output pins return 1 from gpio_function() [OK]
