I'm reviewing; this code doesn't work on my mac, I can't figure out the problem.

It runs perfectly fine on workspaces.

sodas = ["Pepsi", "Diet coke", "Orange Soda"]
candy = ["Twizzlers", "Snickers Bar", "Candy Crush"]
chips = ["Potatos", "Barbeque Chips", "Pringles"]

while True:
        choice = input("Do you want a CANDY, CHIPS or SODA? ")
        if choice == 'chips':
            snack = chips.pop()
        elif choice == 'soda':
            snack = sodas.pop()
        elif choice == 'candy':
            snack = candy.pop()
            print("Sorry, I don't understand that")
    except IndexError:
        print("Sorry, we are out of {}".format(choice))
        print("Here's your {}: {}".format(choice, snack))

Your code works correctly for me on my Windows machine (although it goes on forever because there's no break clause to exit the loop).

My best guess as to why it doesn't work on your Mac would be that you are using an older version of Python - I believe Python 2.x comes installed on Mac OS by default, and the code above will only work on Python 3.x, which you can download here:

Yeah Stuart, I had the same realization this morning - it works when I run "python3 ......" Thanks!
