Instructions

Azara and Rui are teammates competing in a pirate-themed treasure hunt. One has a list of treasures with map coordinates, the other a list of location names with map coordinates. They've also been given blank maps with a starting place marked YOU ARE HERE.


Azara's List Rui's List
Treasure Coordinates
Amethyst Octopus 1F
Angry Monkey Figurine 5B
Antique Glass Fishnet Float 3D
Brass Spyglass 4B
Carved Wooden Elephant 8C
Crystal Crab 6A
Glass Starfish 6D
Model Ship in Large Bottle 8A
Pirate Flag 7F
Robot Parrot 1C
Scrimshawed Whale Tooth 2A
Silver Seahorse 4E
Vintage Pirate Hat 7E
Location Name Coordinates Quadrant
Seaside Cottages ("1", "C") Blue
Aqua Lagoon (Island of Mystery) ("1", "F") Yellow
Deserted Docks ("2", "A") Blue
Spiky Rocks ("3", "D") Yellow
Abandoned Lighthouse ("4", "B") Blue
Hidden Spring (Island of Mystery) ("4", "E") Yellow
Stormy Breakwater ("5", "B") Purple
Old Schooner ("6", "A") Purple
Tangled Seaweed Patch ("6", "D") Orange
Quiet Inlet (Island of Mystery) ("7", "E") Orange
Windswept Hilltop (Island of Mystery) ("7", "F") Orange
Harbor Managers Office ("8", "A") Purple
Foggy Seacave ("8", "C") Purple

But things are a bit disorganized: Azara's coordinates appear to be formatted and sorted differently from Rui's, and they have to keep looking from one list to the other to figure out which treasures go with which locations. Being budding pythonistas, they have come to you for help in writing a small program (a set of functions, really) to better organize their hunt information.

1. Extract coordinates

Implement the get_coordinate() function that takes a (treasure, coordinate) pair from Azara's list and returns only the extracted map coordinate.

>>> get_coordinate(('Scrimshawed Whale Tooth', '2A'))
2A

2. Format coordinates

Implement the convert_coordinate() function that takes a coordinate in the format "2A" and returns a tuple in the format ("2", "A").

>>> convert_coordinate("2A")
("2", "A")

3. Match coordinates

Implement the compare_records() function that takes a (treasure, coordinate) pair and a (location, coordinate, quadrant) record and compares coordinates from each. Return True if the coordinates "match", and return False if they do not. Re-format coordinates as needed for accurate comparison.

>>> compare_records(('Brass Spyglass', '4B'), ('Seaside Cottages', ('1', 'C'), 'blue'))
False

>>> compare_records(('Model Ship in Large Bottle', '8A'), ('Harbor Managers Office', ('8', 'A'), 'purple'))
True

4. Combine matched records

Implement the create_record() function that takes a (treasure, coordinate) pair from Azara's list and a (location, coordinate, quadrant) record from Rui's list and returns (treasure, coordinate, location, coordinate, quadrant) if the coordinates match. If the coordinates do not match, return the string "not a match". Re-format the coordinate as needed for accurate comparison.

>>> create_record(('Brass Spyglass', '4B'), ('Abandoned Lighthouse', ('4', 'B'), 'Blue'))
('Brass Spyglass', '4B', 'Abandoned Lighthouse', ('4', 'B'), 'Blue')

>>> create_record(('Brass Spyglass', '4B'), (('1', 'C'), 'Seaside Cottages', 'blue'))
"not a match"

5. "Clean up" & make a report of all records

Clean up the combined records from Azara and Rui so that there's only one set of coordinates per record. Make a report so they can see one list of everything they need to put on their maps. Implement the clean_up() function that takes a tuple of tuples (everything from both lists), looping through the outer tuple, dropping the unwanted coordinates from each inner tuple and adding each to a 'report'. Format and return the 'report' so that there is one cleaned record on each line.

>>> clean_up((('Brass Spyglass', '4B', 'Abandoned Lighthouse', ('4', 'B'), 'Blue'), ('Vintage Pirate Hat', '7E', 'Quiet Inlet (Island of Mystery)', ('7', 'E'), 'Orange'), ('Crystal Crab', '6A', 'Old Schooner', ('6', 'A'), 'Purple')))

"""
('Brass Spyglass', 'Abandoned Lighthouse', ('4', 'B'), 'Blue')\n
('Vintage Pirate Hat', 'Quiet Inlet (Island of Mystery)', ('7', 'E'), 'Orange')\n
('Crystal Crab', 'Old Schooner', ('6', 'A'), 'Purple')\n
