# Functions and Variables
# def = define; def indicates you're creating the function
# named cheese_and_crackers. This function has two arguments:
# cheese_count and boxes_of_crackers
def cheese_and_crackers(cheese_count, boxes_of_crackers):
    # The first two print statements print the value of the args. 
    # The values 20 and 30 respectively. 
    print(f"You have {cheese_count} cheeses!")
    print(f"You have {boxes_of_crackers} boxes of crackers!")
    print("Man that's enough for a party!")
    print("Get a blanket. \n")
