what am i doing wrong?

it says that the output needs to be a list. how is it not a list?

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': 'Benjamin', 'food': 'PB&J sandwhiches'}, {'name': 'Heather', 'food': 'pasta'}, {'name': 'Chris', 'food': 'chips'}]
def string_factory(values):
    new_list = []
    for items in values:
        new_template = template.format(**items)
        final = new_list.append(new_template)
    return final

Hi, In regards to the output not being a list. The new_list.append() method actually doesn't return a value. Rather it just updates the list stored in the new_list variable.

As such, you don't need to set final = new_list.append. But rather you just need to return new_list

I hope this helps!

Regards
