What is the output of this altitude check code?

Given the drone altitude limits set between 10 and 120 meters, what will the program print when the altitude is 130?

Drone Programming

min_altitude = 10
max_altitude = 120
current_altitude = 130
if current_altitude < min_altitude:
    print("Below minimum altitude")
elif current_altitude > max_altitude:
    print("Above maximum altitude")
else:
    print("Altitude within limits")

A Above maximum altitude

B Below minimum altitude

C Altitude within limits

D No output

💡 Hint

Check the condition that compares current altitude with max altitude.

The current altitude (130) is greater than the max altitude (120), so the program prints 'Above maximum altitude'.

❓ Predict Output

What is the value of 'safe_to_fly' after running this code?

The drone must fly only if altitude is between 20 and 100 meters inclusive. What is the value of 'safe_to_fly' if altitude is 20?

Drone Programming

min_altitude = 20
max_altitude = 100
altitude = 20
safe_to_fly = min_altitude <= altitude <= max_altitude

A False

B True

C None

D Error

💡 Hint

Check if the altitude is within the inclusive range.

Since altitude is exactly the minimum limit (20), the condition is true and 'safe_to_fly' is True.

🔧 Debug

What error does this altitude validation code raise?

Identify the error when running this code that checks if altitude is within limits.

Drone Programming

min_altitude = 15
max_altitude = 90
altitude = 50
if altitude > min_altitude and altitude < max_altitude:
    print("Altitude OK")
else:
    print("Altitude out of range")

A NameError: name 'altitude' is not defined

B TypeError: unsupported operand type(s) for >

C SyntaxError: expected ':' after else

D No error, prints 'Altitude OK'

💡 Hint

Look carefully at the else statement syntax.

The else statement is missing a colon at the end, causing a SyntaxError.

❓ Predict Output

How many altitude values are stored after this configuration?

The code stores altitude limits in a dictionary for different zones. How many zones are configured?

Drone Programming

altitude_limits = {
    'zone1': (10, 50),
    'zone2': (20, 80),
    'zone3': (15, 60),
    'zone4': (5, 100)
}
print(len(altitude_limits))

A Error

B 3

C 5

D 4

💡 Hint

Count the number of keys in the dictionary.

There are 4 keys (zone1, zone2, zone3, zone4), so len() returns 4.

Which option correctly describes the effect of this altitude limit code snippet?

Consider this code snippet that sets altitude limits and checks a drone's altitude: min_altitude = 30 max_altitude = 90 altitude = 90 if altitude >= min_altitude and altitude <= max_altitude: status = "Safe" else: status = "Unsafe" What is the value of 'status' and why?

A "Safe" because altitude equals the maximum limit and the condition includes equality

B "Safe" because altitude is greater than min_altitude only

C "Unsafe" because altitude equals max_altitude which is not allowed

D "Unsafe" because altitude must be strictly less than max_altitude

💡 Hint

Check the comparison operators used in the condition.

The condition uses >= and <= which include equality, so altitude equal to max_altitude is considered safe.
