My Code work: working on mac - python3

sodas = ["Pepsi", "Coke", "Sprite"] chips = ["Doritos", "Walkers"] candy = ["Snickers", "M&Ms", "Twizzlers"]

while True: choice = input("Would you like SODA, some CHIPS, or CANDY? ").lower()

try:
    if choice == 'sodas':
        snack == sodas.pop()
    elif choice == 'chips':
        snack == chips.pop()
    elif choice == 'candy':
        snack == candy.pop()
    else:
        print("Sorry, I didn't understand that.")
        continue
except IndexError:
    print("We're all out of {}! Sorry!".format(choice))
else:
    print("Here's your {}: {}".format(choice, snack))

input should return a string so I don't see how you got the error that the result is a list. What did you enter?

Some other things:

  • It's confusing that you prompt for SODA but then check for sodas plural
  • There is no means of exiting your loop
  • These lines: snack == sodas.pop() should use an assignment (=) operator

Hi KRIS NIKOLAISEN,

The problem was, as you said These lines: snack == sodas.pop() should use an assignment (=) operator

Thank you!
