Python on Raspberry Pi - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print a message on the Raspberry Pi console.

Raspberry Pi

print([1])

Drag options to blanks, or click blank then click option'

A"Hello, Raspberry Pi!"

BHello, Raspberry Pi!

Cecho "Hello, Raspberry Pi!"

Dprint("Hello, Raspberry Pi!")

💡 Hint

Common Mistakes

Forgetting to put quotes around the message.

Using shell commands like echo inside print.

The print() function requires the message to be inside quotes to print it as text.

2fill in blank

medium

Complete the code to read input from the user on Raspberry Pi.

Raspberry Pi

user_name = [1]("Enter your name: ")

Drag options to blanks, or click blank then click option'

Ainput

Bprint

Cread

Dscan

💡 Hint

Common Mistakes

Using print instead of input.

Using functions not available in Python.

The input() function reads text typed by the user.

3fill in blank

hard

Fix the error in the code to blink an LED connected to GPIO pin 17.

Raspberry Pi

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)

GPIO.output(17, [1])
time.sleep(1)
GPIO.output(17, GPIO.LOW)

Drag options to blanks, or click blank then click option'

AON

BGPIO.HIGH

CTrue

D1

💡 Hint

Common Mistakes

Using boolean True instead of GPIO.HIGH.

Using numeric 1 instead of GPIO.HIGH.

GPIO pins are set HIGH or LOW to turn on or off. Use GPIO.HIGH to turn the LED on.

4fill in blank

hard

Fill both blanks to create a dictionary of sensor readings where keys are sensor names and values are readings above 50.

Raspberry Pi

sensor_data = { [1]: [2] for [1] in sensors if sensors[[1]] > 50 }

Drag options to blanks, or click blank then click option'

Asensor

Breading

Csensors[sensor]

Dsensor_data

💡 Hint

Common Mistakes

Using different variable names for key and value.

Using the dictionary name as key or value.

Use the loop variable sensor as key and sensors[sensor] as value for readings above 50.

5fill in blank

hard

Fill all three blanks to create a dictionary of uppercase sensor names mapped to their readings if readings are above 30.

Raspberry Pi

filtered = { [1]: [2] for [3] in sensors if sensors[[3]] > 30 }

Drag options to blanks, or click blank then click option'

Asensor.upper()

Bsensors[sensor]

Csensor

Dreading

💡 Hint

Common Mistakes

Using wrong variable names for keys or values.

Not converting sensor names to uppercase.

Use sensor.upper() as key, sensors[sensor] as value, and sensor as loop variable.
