So confused with this part...

So confused with pack & unpack.

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!"]
dict = [{"name": "Ronald", "food": "tacos"}, {"name": "Peter", "food": "Shit"}]
template = "Hi, I'm {name} and I love to eat {food}!"

def string_factory(name=None, food=None):
    result_list = []
    for items in dict:
        result_list.append(template.format(**dict))
    return result_list

Thank you Alex, I knew it was something. So would using dict as a variable cause problems in this case?

Yes. It still would cause errors. You can;t use that as a name. ;)

def string_factory(name=None, food=None): # need a dict parameter
    result_list = []
    for items in dict: # dict might not work, it is a keyword
        result_list.append(template.format(**dict)) # maybe format items
    return result_list

Actually, dict is a function :)
