Python Python Collections (2016, retired 2019) Dictionaries String Formatting with Dictionaries

How to unpack dict in function and then use values from it in .format()?

How to unpack dict in function and then use values from it in .format()? I found some answers from a year ago, but it appears the problem has changed enough that it doesn't quite work.

In the video, he only explained how to use the values if you used the ** in calling the function, not how to do it in the function.

Thanks, Sarah

string_factory.py
def favorite_food(dict):

    return "Hi, I'm {name} and I love to eat {food}!".format(name, food)

If you look at the example mentioned in the challenge;

"Hi, I'm {name} and I love to eat {food}!".format(name="Kenneth", food="tacos")

You provide some key word arguments to the format function. If you are provided with a dictionary, in order to extract the same keyword arguments you the ** operator on the dictionary. So in your case you only need to unpack your dictionary like this;

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

oh my goodness, that is so much simpler than all the almost answers I found on other forums and here. thank you
