1fill in blank

easy

Complete the code to define a wearable device's main function.

💡 Hint

Common Mistakes

Forgetting to put quotes around the string.

Returning a number instead of a string.

The function should return a string describing the device. Strings must be in quotes.

Complete the code to check if a wearable device is active.

Intro to Computing

is_active = [1]
if is_active:
    print("Device is on")

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

Afalse

B"yes"

C1

DTrue

💡 Hint

Common Mistakes

Using a string "yes" instead of the boolean True.

Using lowercase true or false which are not valid in Python.

Boolean True means the device is active. It must be capitalized in Python.

hard

Fix the error in the code to correctly calculate battery percentage.

Intro to Computing

battery_level = 80
max_battery = 100
percentage = battery_level [1] max_battery * 100
print(percentage)

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

C+

D*

💡 Hint

Common Mistakes

Using addition or subtraction instead of division.

Multiplying battery_level by max_battery directly.

To find the percentage, divide battery_level by max_battery, then multiply by 100.

4fill in blank

hard

Fill both blanks to create a dictionary of wearable devices and their battery levels.

Intro to Computing

devices = {"watch": [1], "earbuds": [2]

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

A85

B"active"

C90

D"off"

💡 Hint

Common Mistakes

Using strings like "active" instead of numbers.

Mixing numbers and strings incorrectly.

Battery levels are numbers, so use 85 and 90 without quotes.

5fill in blank

hard

Fill both blanks to filter devices with battery above 50%.

Intro to Computing

filtered = {k: v for k, v in devices.items() if v [1] [2]
print(filtered)

# Expected output: {'watch': 85, 'earbuds': 90}

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

A>

B50

C<

D==

💡 Hint

Common Mistakes

Using less than or equal instead of greater than.

Using equality instead of comparison.

The code filters devices where battery level (v) is greater than 50.
