I'm not sure what I'm supposed to do for this code challenge?

It says the function is supposed accept a dictionary as an argument, unpack it, and pass it to the format method as keywords. I can't figure this out. How do you do this?

string_factory.py 
def favorite_food(dict):
    return "Hi, I'm {name} and I love to eat {food}!".format()

Yeah-- this is a little confusing. It requires 2 things, knowing how to unpack the dict key/value pairs and using "named arguments" in the string format() method.

I would not typically code this way, but you can see what Kenneth was hoping you'd try out. Note that the line is pretty long and might wrap on your screen display.

See below.

def favorite_food(dict):
    return "Hi, I'm {name} and I love to eat {food}!".format(name=dict['name'], food=dict['food'])
