wont print final else statement

I can't get it to print my final else statement. what am I doing wrong

soda = ['coke','pepsi','dew'] chips = ['fritos', 'doritos'] candy = ['twizzler', 'starburst', 'twix']

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

try:
    if choice == 'soda':
        snack = soda.pop()
    elif choice == 'chips':
        snack = chips.pop()
    elif choice == 'candy':
        snack = candy.pop()
    else:
        print("sorry i didnt understand that.")
        continue

except IndexError:
    print("sorry all out of {}".format(choice))

I've just run your code on a local file on my system and the script is working perfectly for me.

Try typing anything that doesn't appear in any of your arrays.

hmmm still doesn't work in my workspace. odd. thank you for the check

Hi Vincent, my guess is that the program will never reach that last line: the else statement...After the continue statement it jumps back at the top of the loop and if it throws a IndexError it will hande it by printing "sorry all out of {itemname}" then it will go back at the top of the loop again never reaching that last Else statement.

I copied and pasted your code : All I did is delete the else: key word at the end of your code, then I moved up your print("here is your {}: {}".format(choice, snack)) in the try block under the continue line.

I would love to have another opinion on this as I'm no expert...Yet...Maybe one day ;) But I'm willing to bet 10 myrrh that last else statement will never see daylight if you leave it there. It will jump right back in that loop and never run that line.

Here's your code so you can see what I did.

soda = ['coke','pepsi','dew']
chips = ['fritos', 'doritos']
candy = ['twizzler', 'starburst', 'twix']

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

    try:
        if choice == 'soda':
            snack = soda.pop()
        elif choice == 'chips':
            snack = chips.pop()
        elif choice == 'candy':
            snack = candy.pop()
        else:
            print("sorry i didnt understand that.")
            continue
        print("here is your {}: {}".format(choice, snack))

    except IndexError:
        print("sorry all out of {}".format(choice))
