Hi I have completed this project but at the end, I am getting error: TypeError: must be str, not list

My script.py file is here:
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

attractions =
for destination in destinations:
attractions.append()

def add_attraction(destination, attraction):
destination_index = get_destination_index(destination)
attractions_for_destination = attractions[destination_index].append(attraction)

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”, “historical 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:
    attractions_with_interest.append(possible_attraction)

return attractions_with_interest

def get_attractions_for_traveler(traveler):
traveler_destination = traveler[1]
traveler_interests = traveler[2]
traveler_attractions = find_attractions(traveler_destination, traveler_interests)

interests_string = "Hi " + traveler[0] + ", we think you’ll like these places around " + traveler_destination + ": "
for i in range(len(traveler_attractions)):
if traveler_attractions[-1] == traveler_attractions[i]:
interests_string += "the " + traveler_attractions[i] + ". "
else:
interests_string += "the " + traveler_attractions[i] + ", "
return interests_string

smills_france = get_attractions_for_traveler([‘Dereck Smill’, ‘Paris, France’, [‘monument’]])

print(smills_france)

Could you please help me to solve it!
Thank you.

I’d be happy to try, if you’ll re-post your code with its original formatting intact. See How do I format code in my posts?
It would also be very helpful if you post the entire actual error message that shows the line of code where the error was thrown.

Here I am posing link for my project code. I really need to know where I need to correct my code.

Thank you.

From your code:

def get_attractions_for_traveler(traveler):
  traveler_destination = traveler[1]
  traveler_interests = traveler[2]
  traveler_attractions = find_attractions(traveler_destination, traveler_interests)

  interests_string = "Hi " + traveler[0] + ", we think you'll like these places around " + traveler_destination + ": "
  for i in range(len(traveler_attractions)):
    print(traveler_attractions[i]) #debug print
    if traveler_attractions[-1] == traveler_attractions[i]:
      interests_string += "the " + traveler_attractions[i] + ". "
    else: 
      interests_string += "the " + traveler_attractions[i] + ", "
  return interests_string

The error is thrown when this function is executed. Specifically when you attempt to concatenate traveler_attractions[i] to interests_string. The error message tells you exactly what the problem is. You can’t concatenate a list to a string. Try printing traveler_attractions[i] prior to the line that concatenates it to the string. (See above if needed.) Is the value what you expected?
