To run the above code, you need to create another pizza.py

def make_pizza (Size, *toppings): "    Overview of the pizza to be made"    print ("Do a size:" + str (size) + ", contains:") for topping in    Toppin GS:        Print ("-" + topping)    print ("pizza") def get_price ():    print ("The Price is 20")
