💡 Hint

Common Mistakes

Using 'stopSpraying' instead of 'startSpraying'.

Using 'hover' which only makes the drone stay in place.

Using 'land' which makes the drone land instead of spraying.

The startSpraying() method activates the drone's spraying system to begin applying pesticides or fertilizers.

Complete the code to check the drone's battery level before spraying.

Drone Programming

if drone.getBatteryLevel() [1] 20:
    drone.returnToBase()

💡 Hint

Common Mistakes

Using '>' which would return to base when battery is high.

Using '==' which only triggers at exactly 20%.

Using '>=' which triggers when battery is high or equal.

The drone should return to base if the battery level is less than or equal to 20% to avoid running out of power during spraying.

Fix the error in the code to correctly log the spray area coverage.

Drone Programming

coverage = drone.getSprayArea()
print('Coverage:', coverage[1]'%')

💡 Hint

Common Mistakes

Using ',' which separates arguments but does not concatenate.

Using '*' which causes a type error.

Using '-' which is invalid for strings.

The plus sign + concatenates the coverage value with the percent sign to form a complete string.

Fill both blanks to create a dictionary of field zones with their spray status.

Drone Programming

zones_status = {zone: drone.[1](zone) for zone in field_zones if drone.[2](zone)}

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

DstopSpraying

💡 Hint

Common Mistakes

Using 'startSpraying' or 'stopSpraying' which control spraying, not status.

Swapping the two methods causing logic errors.

isSprayed(zone) checks if a zone has been sprayed, and checkSprayed(zone) returns the spray status for the zone.

5fill in blank

hard

Fill all three blanks to create a filtered dictionary of zones needing spraying with their moisture levels.

Drone Programming

zones_to_spray = {zone[1]: drone.[2](zone) for zone in field_zones if drone.[3](zone) < 30}

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

BgetMoistureLevel

D.lower()

💡 Hint

Common Mistakes

Using '.lower()' instead of '.upper()' for keys.

Using different methods for moisture level causing errors.

Not filtering zones correctly by moisture.

The dictionary keys are zone names converted to uppercase (.upper()), the values are moisture levels from getMoistureLevel(zone), and the filter selects zones with moisture below 30.
