whats does this error mean

I've googled this, and what it tell me is that im attempting to call out the incorrect number of arguments, i guess im just not understanding

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!"]
value = [{"name": "michelangelo", "food": "Pizza"}, {"name": "Garfield", "food": "lasagna"}]

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

def string_factory(value, string):
    strings = []

    for x in value:
        strings.append(string.format(**x))

    return strings

string_factory() missing 1 required positional argument: 'string' is the error

You're very close. The challenge doesn't want you pass the template string into the function. It should be defined outside. This one change gets your code to pass the challenge:

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

def string_factory(value):
    strings = []

    for x in value:
        strings.append(template.format(**x))

    return strings
