[Solved] Identify the error in this Raspberry Pi watering system code snippet:import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(17, GPIO.OUT) soil_moisture = 500 if soil_moisture > 400 GPIO.... | Raspberry Pi

Raspberry Pi - Automation and Scheduling

Identify the error in this Raspberry Pi watering system code snippet:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)
soil_moisture = 500
if soil_moisture > 400
    GPIO.output(17, GPIO.LOW)
    print("Pump OFF")

Asoil_moisture value is invalid

BMissing colon (:) after if condition

CGPIO.output should be GPIO.setup

DWrong GPIO pin number

Step-by-Step Solution

Solution:

Step 1: Check if statement syntax
Python requires a colon (:) after the if condition.
Step 2: Identify missing colon error
The code misses ':' after 'if soil_moisture > 400', causing syntax error.
Final Answer:
Missing colon (:) after if condition -> Option B
Quick Check:
if statement needs ':' = D [OK]

Quick Trick: Always put ':' after if conditions in Python [OK]

Common Mistakes:

MISTAKES

Forgetting colon after if
Confusing GPIO.output with GPIO.setup
Assuming pin number is wrong
