💡 Hint

Common Mistakes

Using fly() instead of goto().

Using move() which is not a valid command.

The goto() command directs the drone to fly to the specified coordinates.

Complete the code to make the drone go to the point stored in variable target.

Drone Programming

drone.[1](target.x, target.y, target.z)

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

💡 Hint

Common Mistakes

Using commands like flyTo() which do not exist.

Passing the whole target object instead of its coordinates.

goto() is used to send the drone to specific coordinates, here taken from the target object.

💡 Hint

Common Mistakes

Using colons or semicolons instead of commas.

Missing commas between arguments.

Arguments in function calls must be separated by commas.

4fill in blank

hard

Fill both blanks to create a dictionary of points with their altitudes using goto().

Drone Programming

points = {name: drone.[1](coords[0], coords[1], [2]) for name, coords in locations.items()}

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

💡 Hint

Common Mistakes

Using incorrect command names like altitude.

Using wrong altitude values like height.

The goto() command is used to send the drone to x, y, and z coordinates. The altitude is the third coordinate coords[2].

5fill in blank

hard

Fill all three blanks to filter points above altitude 50 and send the drone there.

Drone Programming

high_points = {name: drone.[1](x, y, z) for name, (x, y, z) in points.items() if z [2] 50 and name.[3]('A')}

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

Agoto

Cstartswith

Dfly

💡 Hint

Common Mistakes

Using wrong command like fly().

Using wrong comparison operators like <.

Using incorrect string methods.

goto() sends the drone to the point. The filter checks if altitude z is greater than 50 and the name starts with 'A'.

Practice

1. What does the goto(x, y, z, speed) command do in drone programming?

easy

A. Moves the drone to the specified coordinates at the given speed.

B. Starts the drone's camera recording.

C. Lands the drone immediately.

D. Turns the drone around 360 degrees.

Solution

1. Step 1: Understand the purpose of goto()

   The goto() command is designed to move the drone to a specific location using coordinates.

2. Step 2: Analyze the parameters

   The parameters x, y, z represent the position in space, and speed controls how fast the drone moves there.

3. Final Answer:

   Moves the drone to the specified coordinates at the given speed. -> Option A

4. Quick Check:

   goto() moves drone = A [OK]

Hint: Remember: goto() moves drone to coordinates fast or slow [OK]

Common Mistakes:

• Confusing goto() with camera or landing commands
• Ignoring the speed parameter
• Thinking goto() rotates the drone

2. Which of the following is the correct syntax to move a drone to position (10, 20, 5) at speed 3 using goto()?

easy

A. goto(10, 20, 3, 5)

B. goto(10, 20, 5, 3)

C. goto(3, 10, 20, 5)

D. goto(5, 3, 10, 20)

Solution

1. Step 1: Identify parameter order

   The goto() command takes parameters in order: x, y, z, speed.

2. Step 2: Match values to parameters

   Given position (10, 20, 5) and speed 3, the correct call is goto(10, 20, 5, 3).

3. Final Answer:

   goto(10, 20, 5, 3) -> Option B

4. Quick Check:

   Order is x,y,z,speed = C [OK]

Hint: Remember parameter order: x, y, z, then speed [OK]

Common Mistakes:

• Mixing up speed with coordinate values
• Changing parameter order
• Using wrong numbers for coordinates

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

goto(5, 5, 10, 2)
goto(10, 10, 5, 4)

medium

A. (0, 0, 0)

B. (5, 5, 10)

C. (15, 15, 15)

D. (10, 10, 5)

Solution

1. Step 1: Execute first goto()

   The drone moves to coordinates (5, 5, 10) at speed 2.

2. Step 2: Execute second goto()

   The drone then moves to (10, 10, 5) at speed 4, which is the final position.

3. Final Answer:

   (10, 10, 5) -> Option D

4. Quick Check:

   Last goto() position = A [OK]

Hint: Last goto() sets final position, earlier ones are overwritten [OK]

Common Mistakes:

• Adding coordinates instead of replacing
• Ignoring the second goto()
• Confusing speed with position

4. Identify the error in this code snippet:

goto(10, 20, speed=5, 3)

medium

A. Speed parameter is given before z coordinate.

B. No error; code is correct.

C. Using named argument for speed but position parameters are positional.

D. Missing one coordinate parameter.

Solution

1. Step 1: Check parameter usage

   The code mixes positional and named arguments incorrectly by placing speed=5 before the last positional argument.

2. Step 2: Understand Python argument rules

   Positional arguments must come before named arguments; here, 3 is positional after a named argument, causing a syntax error.

3. Final Answer:

   Using named argument for speed but position parameters are positional. -> Option C

4. Quick Check:

   Named args after positional = D [OK]

Hint: Named arguments must come after all positional ones [OK]

Common Mistakes:

• Placing named arguments before positional
• Assuming order doesn't matter
• Missing commas between parameters

5. You want the drone to inspect three points in order: (0,0,5), (10,0,5), and (10,10,5), each at speed 2. Which code correctly uses goto() to do this?

hard

A. goto(0, 0, 5, 2)
goto(10, 0, 5, 2)
goto(10, 10, 5, 2)

B. goto([0,0,5], 2)
goto([10,0,5], 2)
goto([10,10,5], 2)

C. goto(0, 0, 5)
goto(10, 0, 5)
goto(10, 10, 5)

D. goto(0, 0, 5, 2, 3)
goto(10, 0, 5, 2, 3)
goto(10, 10, 5, 2, 3)

Solution

1. Step 1: Check parameter correctness

   Each goto() call must have four parameters: x, y, z, and speed.

2. Step 2: Validate each option

   goto(0, 0, 5, 2) goto(10, 0, 5, 2) goto(10, 10, 5, 2) correctly uses four parameters per call. goto([0,0,5], 2) goto([10,0,5], 2) goto([10,10,5], 2) uses lists instead of separate coordinates. goto(0, 0, 5) goto(10, 0, 5) goto(10, 10, 5) misses speed. goto(0, 0, 5, 2, 3) goto(10, 0, 5, 2, 3) goto(10, 10, 5, 2, 3) has an extra parameter.

3. Final Answer:

   goto(0, 0, 5, 2) goto(10, 0, 5, 2) goto(10, 10, 5, 2) -> Option A

4. Quick Check:

   Correct parameters and order = B [OK]

Hint: Use four parameters: x, y, z, speed for each goto() [OK]

Common Mistakes:

• Passing coordinates as a list instead of separate values
• Omitting speed parameter
• Adding extra parameters
