CS101: Introduction to programming. The Boredless tourist project

I am currently doing this project → https://www.codecademy.com/paths/computer-science/tracks/cspath-cs-101/modules/cspath-boredless-tourist/projects/the-boredless-tourist

In “Stept 48” when print(la_arts) I obtain: [[‘LACMA’, [‘art’, ‘museum’]], [‘LACMA’, [‘art’, ‘museum’]]] . I don’t understand why do I obtain [["LACMA, [“art”, “museum”]]] twice instead of one.

This is my current code:

destinations = ["Paris, France", "Shanghai, China", "Los Angeles, USA", "São Paulo, Brazil", "Cairo, Egypt"]
test_traveler = ["Erin Wilkes", "Shanghai, China", ["historical site", "art"]]
def get_destination_index (destination):
  destination_index = destinations.index(destination)
  return destination_index

def get_traveler_location(traveler):
  traveler_destination = traveler[1]
  traveler_destination_index = get_destination_index(traveler_destination)
  return traveler_destination_index
test_destination_index = get_traveler_location(test_traveler) 

attractions = [[], [], [], [], []]
def add_attraction (destination, attraction):
    destination_index = get_destination_index(destination)
    attractions_for_destination = attractions[destination_index]
add_attraction("Los Angeles, USA", ['Venice Beach', ['beach']])
add_attraction("Paris, France", ["the Louvre", ["art", "museum"]])
add_attraction("Paris, France", ["Arc de Triomphe", ["historical site", "monument"]])
add_attraction("Shanghai, China", ["Yu Garden", ["garden", "historcical site"]])
add_attraction("Shanghai, China", ["Yuz Museum", ["art", "museum"]])
add_attraction("Shanghai, China", ["Oriental Pearl Tower", ["skyscraper", "viewing deck"]])
add_attraction("Los Angeles, USA", ["LACMA", ["art", "museum"]])
add_attraction("São Paulo, Brazil", ["São Paulo Zoo", ["zoo"]])
add_attraction("São Paulo, Brazil", ["Pátio do Colégio", ["historical site"]])
add_attraction("Cairo, Egypt", ["Pyramids of Giza", ["monument", "historical site"]])
add_attraction("Cairo, Egypt", ["Egyptian Museum", ["museum"]])

def find_attractions(destination, interests):
  destination_index = get_destination_index(destination)
  attractions_in_city = attractions[destination_index]
  attractions_with_interest = []
  for attraction in attractions_in_city:
    possible_attraction = attraction
    attraction_tags = attraction[1]
    for interest in interests:
      if interest in attraction_tags:
  return attractions_with_interest

la_arts = find_attractions("Los Angeles, USA", ["art", "museum"])

Thanks so much.

Welcome to the Get Help category!

This is where you can ask questions about your code. Some important things to remember when posting in this category :slight_smile:

  • Once you understand a new concept, come back and try to help someone else!


I’d work backwards from your function calls leaving f-string print statements to clarify what’s going on. Additionally, it’s useful when using try/except blocks to actually have the except be explicitly for the error you’re expecting. This is because if it it’s an error you’re not expecting it’s harder to track down later!


>>> s = "hello, world"
>>> print(f'my string: {s}')
my string: hello, world
