Odd problem in Python Collections: Vending Machine Code

When running my code for the python "vending machine" I asked for chips for the first time and got this back:

Here's your chips: <built-in method pop of list object at 0x7f9f43437d08>

Oddly enough, the code then continued without an error. I've checked the code multiple times as well as made sure I saved it, but it seems to me there are no problems with it.

Here's a link to the video:

Also, it seems to work just fine for sodas and and candy.

Can you post your code, please?

Sure, here it is:

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

while True:

choice = input("Would you like SODA, some CHIPS, or a CANDY").lower()
    try:
        if choice == "soda":
            snack = sodas.pop()
        elif choice == "chips":
            snack = chips.pop
        elif choice == "candy":
            snack = candy.pop()
        else:
            print("Sorry, we don't have that!")
            continue
    except IndexError:
        print("We're all out of {}! So Sorry!".format(choice))
    else:        
        print("Here's your {}: {}".format(choice, snack))

Thanks!

You are missing the parentheses on your pop method for chips 

snack = chips.pop

should be

snack = chips.pop()

Yikes! Can't believe I missed that! All makes sense now. Thanks!
