Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a GPS coordinate with latitude 40.7128.

Drone Programming

coordinate = {'latitude': [1], 'longitude': -74.0060, 'altitude': 10}

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

💡 Hint

Common Mistakes

Confusing latitude with longitude.

Using altitude value for latitude.

The latitude value is 40.7128, which represents the north-south position.

medium

Complete the code to print the longitude from the coordinate dictionary.

Drone Programming

print(coordinate[[1]])

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

A'longitude'

B'altitude'

C'location'

D'latitude'

💡 Hint

Common Mistakes

Using 'latitude' instead of 'longitude'.

Forgetting quotes around the key.

Longitude is accessed by the key 'longitude' in the coordinate dictionary.

3fill in blank

hard

Fix the error in the code to correctly update the altitude to 20.

Drone Programming

coordinate[[1]] = 20

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

A'altitude'

B'height'

💡 Hint

Common Mistakes

Using key without quotes causing a NameError.

Using wrong key name.

Dictionary keys must be strings in quotes to update the value correctly.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that stores coordinates with altitude above 15.

Drone Programming

{coord['latitude']: coord[[1]] for coord in coordinates if coord[[2]] > 15}

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

A'altitude'

B'longitude'

C'latitude'

D'height'

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong keys like 'longitude' or 'height'.

Mixing keys between blanks.

We filter coordinates where altitude is greater than 15 and map latitude to altitude.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping latitude to longitude for coordinates below altitude 50.

Drone Programming

{coord[[1]]: coord[[2]] for coord in coordinates if coord[[3]] < 50}

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

A'latitude'

B'longitude'

C'altitude'

D'height'

Attempts:

💡 Hint

Common Mistakes

Using wrong keys in mapping or condition.

Confusing altitude with height.

The dictionary maps latitude to longitude for coordinates where altitude is less than 50.
