1fill in blank

easy

Complete the code to define a drone's basic takeoff function.

Drone Programming

def takeoff():
    print("Drone is [1]")

💡 Hint

Common Mistakes

Using 'landing' or 'charging' instead of 'taking off'.

The function prints that the drone is taking off, which is the correct action for a takeoff function.

Complete the code to check if the drone's battery level is sufficient for flight.

Drone Programming

if battery_level [1] 20:
    print("Battery low, please recharge.")

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

A<=

B>

C==

D!=

Attempts:

3 left

💡 Hint

Common Mistakes

Using '>' instead of '<=' which would check for high battery.

The code checks if the battery level is less than or equal to 20 to warn about low battery.

Fix the error in the drone's altitude adjustment code.

Drone Programming

altitude [1] 5

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

A+=

B/=

C*=

D-=

Attempts:

💡 Hint

Common Mistakes

Using '-' which decreases altitude instead of increasing it.

The '+=' operator correctly increases the altitude by 5 units.

4fill in blank

hard

Fill both blanks to create a dictionary of drone models and their max flight times.

Drone Programming

flight_times = {"ModelA": [1], "ModelB": [2]

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

A30

B45

C60

D15

Attempts:

3 left

💡 Hint

Common Mistakes

Using strings instead of numbers for flight times.

The dictionary maps ModelA to 30 minutes and ModelB to 45 minutes of max flight time.

5fill in blank

hard

Fill all three blanks to filter drones with battery life greater than 40 and create a new dictionary.

Drone Programming

filtered_drones = [1]: [2] for [3], [2] in drones.items() if [2] > 40}

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

💡 Hint

Common Mistakes

Mixing variable names or using undefined variables.

The code creates a dictionary with model names as keys and battery values as values, filtering those with battery > 40.

Practice

1. Which of the following is a common career opportunity related to drone programming?

easy

A. Developing software to control drone flight paths

B. Designing drone packaging materials

C. Selling drone insurance policies

D. Writing drone user manuals

Solution

1. Step 1: Understand drone programming roles

   Drone programming involves creating software that controls drones, such as flight paths and sensors.

2. Step 2: Identify the option related to programming

   Developing software to control drone flight paths describes developing software for drone flight, which matches drone programming.

3. Final Answer:

   Developing software to control drone flight paths -> Option A

4. Quick Check:

   Drone programming = software development [OK]

Hint: Look for software-related tasks in drone careers [OK]

Common Mistakes:

• Confusing hardware roles with programming
• Choosing options unrelated to software
• Ignoring the programming focus

2. Which of these is the correct syntax to define a function in a drone programming script using Python?

easy

A. function flyDrone():

B. define flyDrone()

C. func flyDrone()

D. def flyDrone():

Solution

1. Step 1: Recall Python function syntax

   In Python, functions are defined using the keyword def followed by the function name and parentheses.

2. Step 2: Match options to Python syntax

   def flyDrone(): uses def flyDrone():, which is correct Python syntax.

3. Final Answer:

   def flyDrone(): -> Option D

4. Quick Check:

   Python function = def [OK]

Hint: Python functions start with 'def' keyword [OK]

Common Mistakes:

• Using 'function' like JavaScript
• Using 'func' or 'define' which are invalid in Python
• Missing colon at the end

3. What will be the output of this Python code snippet used in drone programming?

commands = ['takeoff', 'forward', 'left', 'land']
for i, cmd in enumerate(commands):
    print(f"Step {i+1}: {cmd}")

medium

A. Step 1: takeoff\nStep 2: forward\nStep 3: left\nStep 4: land

B. Step 0: takeoff\nStep 1: forward\nStep 2: left\nStep 3: land

C. Step 1: takeoff\nStep 2: forward\nStep 3: left

D. Error: enumerate not defined

Solution

1. Step 1: Understand enumerate usage

   enumerate(commands) returns pairs of (index, command) starting at 0.

2. Step 2: Analyze print statement

   Print uses i+1 for step number, so steps start at 1, printing all commands.

3. Final Answer:

   Step 1: takeoff\nStep 2: forward\nStep 3: left\nStep 4: land -> Option A

4. Quick Check:

   Index + 1 = step number [OK]

Hint: Remember enumerate starts at 0; add 1 for human count [OK]

Common Mistakes:

• Forgetting to add 1 to index
• Missing last command in output
• Assuming enumerate causes error

4. Identify the error in this drone programming Python code snippet:

def start_drone()
    print("Drone started")
start_drone()

medium

A. Indentation error in print statement

B. Incorrect function call syntax

C. Missing colon ':' after function definition

D. Missing parentheses in print function

Solution

1. Step 1: Check function definition syntax

   Python requires a colon ':' after the function header line.

2. Step 2: Verify other syntax elements

   Function call and print statement are correct; parentheses in print are present.

3. Final Answer:

   Missing colon ':' after function definition -> Option C

4. Quick Check:

   Function header needs ':' [OK]

Hint: Function headers always end with ':' in Python [OK]

Common Mistakes:

• Ignoring missing colon
• Thinking print needs parentheses removed
• Assuming indentation is wrong

5. You want to create a dictionary in Python that maps drone model names to their maximum flight time in minutes. Which code correctly creates this dictionary for models 'Alpha' (30 min), 'Beta' (45 min), and 'Gamma' (25 min)?

hard

A. drone_times = {'Alpha' -> 30, 'Beta' -> 45, 'Gamma' -> 25}

B. drone_times = {'Alpha': 30, 'Beta': 45, 'Gamma': 25}

C. drone_times = ('Alpha' = 30, 'Beta' = 45, 'Gamma' = 25)

D. drone_times = ['Alpha': 30, 'Beta': 45, 'Gamma': 25]

Solution

1. Step 1: Recall Python dictionary syntax

   Dictionaries use curly braces with key:value pairs separated by commas.

2. Step 2: Check each option's syntax

   drone_times = {'Alpha': 30, 'Beta': 45, 'Gamma': 25} uses correct syntax with curly braces and colons. Others use invalid brackets or symbols.

3. Final Answer:

   drone_times = {'Alpha': 30, 'Beta': 45, 'Gamma': 25} -> Option B

4. Quick Check:

   Dict = {key: value} [OK]

Hint: Use curly braces and colons for Python dictionaries [OK]

Common Mistakes:

• Using square brackets instead of curly braces
• Using '=' or '->' instead of ':'
• Using parentheses instead of braces
