Output of goto() with simple coordinates

What will be the output of this drone navigation code snippet?

Drone Programming

drone.goto(10, 20, 5)
print(drone.position())

A (10, 20)

B (0, 0, 0)

C (10, 20, 5)

D Error: Invalid coordinates

💡 Hint

The goto() command moves the drone to the specified x, y, z coordinates.

The drone.goto(10, 20, 5) moves the drone to position (10, 20, 5). The position() method returns the current coordinates.

Effect of sequential goto() commands

What will be the drone's final position after running this code?

Drone Programming

drone.goto(5, 5, 5)
drone.goto(10, 0, 0)
print(drone.position())

A (5, 5, 5)

B (0, 0, 0)

C (15, 5, 5)

D (10, 0, 0)

💡 Hint

Each goto() command moves the drone to a new absolute position.

The drone first moves to (5, 5, 5), then moves to (10, 0, 0). The final position is the last goto() coordinates.

Identify the error in goto() usage

This code is intended to move the drone to (10, 10, 10). What error will it cause?

Drone Programming

drone.goto(10, 10)
print(drone.position())

A TypeError: missing 1 required positional argument 'z'

B SyntaxError: invalid syntax

C ValueError: coordinates must be positive

D No error, outputs (10, 10, 0)

💡 Hint

The goto() command requires three coordinates: x, y, and z.

The goto() function expects three arguments. Providing only two causes a TypeError for missing the z coordinate.

Understanding relative vs absolute goto()

Which statement correctly describes the difference between absolute and relative goto() commands?

A Absolute goto() moves the drone by offsets; relative goto() moves it to exact coordinates.

B Absolute goto() moves the drone to exact coordinates; relative goto() moves it by offsets from current position.

C Both absolute and relative goto() move the drone to exact coordinates but use different units.

D Relative goto() moves the drone to the origin; absolute goto() moves it randomly.

💡 Hint

Think about whether the drone moves to a fixed point or moves relative to where it is now.

Absolute goto() uses fixed coordinates. Relative goto() moves the drone by adding offsets to its current position.

Output after complex navigation sequence

What is the final position printed by this code?

Drone Programming

drone.goto(0, 0, 0)
drone.goto(5, 5, 5)
drone.goto(5, 10, 5)
drone.goto(10, 10, 10)
print(drone.position())

A (10, 10, 10)

B (5, 10, 5)

C (0, 0, 0)

D (15, 25, 20)

💡 Hint

Each goto() sets the drone's position absolutely, not cumulatively.

The drone moves step-by-step to each specified coordinate. The last goto() sets the final position.
