is the error I get. I have inputs for the user to type things in, and one of them is a name of a food. I want to capture all of their inputs, and append the name to a list. What am I doing wrong? My whole code is:

tot_cals = 0

    if g_type == "f":
        return grams * 9

        return grams * 4

    for c in range(len(item_list)):
        meal_cals += cals_list[c]
        print("{}.\t{}\t\t{}".format(c+1, item_list[c], cals_list[c]))
    print("\nYour meal has {} items for a total of {} calories\n".format(len(item_list), meal_cals))
    print("-" * 20)
