Write a function named string_factory that accepts a list of dictionaries as an argument. Return a new list of strings m

I'm getting an error that says my output should be a list. I don't understand what I need to change to make it so.

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}!"



def string_factory(name=None, food=None):
    if name and food:
        print("Hi, I'm {} and I love to eat {}!".format(name, food))

string_factory(**{"name": "Austin", "food": ["burritos", "tacos", "pizza"]})

The challenge asks to return a new list, not print it. 

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

def string_factory(args):
    new_list = []
    for dict in args:
        new_list.append(template.format(**dict))
    return new_list

string_factory(values)

If you want to print out the answer in your local python environment so you can see if it works, just substitute print(new_list) for return new_list

your function does not return anything, it just prints a string. change it to return whatever strings it is asking for instead of printing a string.

Can you write out the correct code? I'm so fucking lost on this stuff. I've tried 4 or 5 different things based on the suggestions I've found online, but I'm not understanding it at all.

Truly took me a lot of time to figure it out. Hope this helps:

def string_factory(dic_list):
    template = "Hi, I'm {name} and I love to eat {food}!"
    return_list = []
    for dic in dic_list:
        return_list.append("".join(template.format(**dic)))
    return return_list
