I literally have no idea what to do here. There really isn't enough information in the video to help me finish this.

He sends a dictionary, in a literal way, as an argument in the function parameter. What do i do if i have no idea whats in the dictionary?

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

You can return the key-value pair from the dictionary that's passed in by unpacking it with **. Example:

def function(dict):
    return "{letter} is a letter, and {number} is a number.".format(**dict)

function({"letter" : "A", "number" : 1})

# returns: 
# "A is a letter, and 1 is a number."

For the challenge, you just have to assume that the test will pass in a dictionary that looks something like this: 

{"name" : "Kenneth", "food" : "pie"}

Agreed that the video didn't prepare for this task at all. Very frustrating.
