string_factory.py

It just says Bummer! 'name' ????? I am not sure what I am doing wrong! I have try more than one approach and I can't unpack at the bottom, because it marks it incorrect too. I appreciate the help.

string_factory.py
# Example:
# values = [{"name": "Michelangelo", "food": "PIZZA"}, {"name": "Garfield", "food": "lasagna"}]
# string_factory(values)
# ["Hi, I'm Michelangelo and I love to eat PIZZA!", "Hi, I'm Garfield and I love to eat lasagna!"]

template = "Hi, I'm {name} and I love to eat {food}!"
values = [{"name": "Michelangelo", "food": "PIZZA"}, {"name": "Garfield", "food": "lasagna"}]

def string_factory(name=None, food=None):
    while True:
        name=name
        food=food
        if name and food:
            return template.format(name, food)
string_factory({"name": "Michelangelo", "food": "PIZZA"}, {"name": "Garfield", "food": "lasagna"})

Hey, there's a couple issues in your code.

Your function needs to take a list of dictionaries as it's input. Let's call those values.

def string_factory(values):

It asks us to return a new list of strings, so lets start by making an empty list

   newStrings = []

Since we need to perform an action for each value passed to the function, lets use a loop. Then we can access the name and food properties of the dictionary individually.

  for value in values:
      name = value["name"]
      food = value["food"]

And then we can use the format() function to create our string and append it to our newStrings list.

  formattedString = template.format(name=name, food=food)
  newStrings.append(formattedString)

Lastly we will return our newStrings list. Here's what my code looks like all together.

template = "Hi, I'm {name} and I love to eat {food}!"

def string_factory(values):
  newStrings = []
  for value in values:
      name = value["name"]
      food = value["food"]
        formattedString = template.format(name=name, food=food)
        newStrings.append(formattedString)
  return newStrings;
