    num1=input("Input a number. ")
num2=input("Input a number. ")
num3=input("Input a number. ")
add=input("How much would you like to add? ")
# Add code in the space below
numlist = [num1,num2,num3]
# The following is the code that adds the inputted addend to the other numbers. It is hidden from the user.
for i in [int(a) for a in numlist]:
  numlist[i -1] += int(add)
print(numlist)


    foods = ["pizza", "hot dog", "sushi", "strawberry", "sandwhich"] #simplified foods list
# it is better to use lists because it is more simple
sports1 = "basketball"
sports2= "tennis"
