pop, python collections: console

I try to run the code that is in the console, but Python just creates a new blank line of code without running anything

There are three programs at that URL, but one is entirely blank (shopping_list.py2). Perhaps you forgot to save it?

The other two (Shopping_list.py and Vending_machine.py) look like they'd run/print to the console.

Hey Emilio! You don't have the second part of your try/except block. The except portion should catch an IndexError, for when your list of snacks, drinks, or candies has run out of items. Also, your if statements should be indented under the try:. Additionally, it's nice to add some sort of way to break out of the loop.

candy = ["Chocolate", "Chilli", "Caramel"]
sodas = ["Coke", "Sprite", "fanta"]
chips = ["Lays", "doritos", "salt"]

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

    try:
        if choice == 'done':
            break
        if choice == 'soda':
            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('Sorry, we're out of {}'.format(choice))
    else:
        print("Here's your {}: {}".format(choice, snack))

Hopefully this clears it up for ya!
