packing and unpacking challenge

i've been stuck on this question for awhile, someone please help me figure out whats wrong with my code. Im not 100% sure what the question is asking

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

favorite_food(**{name= "Tyler", food= "steak"})

:warning: Be careful:

  • The function takes a dictionary itself, not keyword arguments.
  • name and food do not exist, but you can pack the dict parameter and pass it into format.
  • You do not need to call the function you wrote, the code checker does it for you.

Here's a solution:

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

Here's an alternative solution:

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

I personally prefer the first solution due to its simplicity and its clearness, but either will do.

I hope this helps :grin:

Happy coding! :zap: ~Alex
