I had issues with using the various links that we were asked to use in the project. For the last problem I could only get my project to work if I used http://localhost:5000/article/my-first-flask-app instead of the . I understand is the same thing as localhost but maybe it’s an issue with my os(manjaro)?

Hello, I have a problem with my Project.
can you help me. I am stuck on #16 task:

from helper import pets
from flask import Flask

app = Flask(__name__)

def index():
  return """
  <h1>Adopt a Pet!</h1>
  <p>Browse through the links below to find your new furry friend:</p>
    <a href="/animals/dogs"><li>Dogs</li>
    <a href="/animals/cats"><li>Cats</li>
    <a href="/animals/rabbits"><li>Rabbits</li>
def animals(pet_type):
  listPets = """<ul>
  for idx, item in enumerate(pets[pet_type]):
    listPets += '<li><a href="">' + item + '</a></li>'
  listPets += "</ul>"
  return f'''
    <a href="/"><h1>List of {pet_type}</h1></a>
    ''' + listPets

def pet(pet_type, pet_id):
  pet = pets[pet_type][pet_id]
  return f'''
  <a href="/">Return to home page</a>

Where I am wrong?

What is the exercise asking you to do. If I were to guess from this it’s to show the different types of formatted strings you can return.

I think this seems redundant here (both an f-string and a formatted string). It doesn’t throw an error but if the exercise is about this they may not like it.

return f'''
  <a href="/">Return to home page</a>

Here is an example to highlight what I’m trying to say:

pet = "dog"

# 'dog'

# 'dog'

# 'dog'
