[XPGKNIGHT]

Hi,

I have a year 7 school project due in 1 week. Cant figure out why it wont work. Please help. The program I use wont tell me where the error is. Does anything stand out?

TOTAL = int(0)

    firstname = input("enter your first name")
    return firstname

drink is not defined it's defined as drinks
The indentation on the elif's is wrong, elif should be at the same indentation as its matching if.

[XPGKNIGHT]

thanks

[jefsummers]

Also in line 81 you have A_DRINKS without parentheses, so it will not call the function. Same problem in 92.

And, your indentation on all of those elif's is wrong

And, can you think of a better way to do this than the large cascade of elifs?

That is some ugly code. You need an abstraction.

Your program has menus, menu items and menu item prices. Your program displays menu items, takes an order, and computes a total. The things your program has are going to become variables. The things your program does are going to become functions. If you come up with a good abstraction for your program's objects (menu, menu items, menu prices) it makes it easy to write the functions that work with these objects. If the functions are well designed it makes it easy to use them to make complicated programs, like taking someone's order.

A menu item is a description of the food. Each menu item has a price. The prices should somehow be associated with the menu item so you can get the price if you know the item. A menu is a collection of menu items. Right now your program doesn't have any code that really represents these things that are central to your program. You have strings for your menu, but the strings include not only the description, but the price, and an order number as well. There is no way to get the price of a menu item.

If I was writing this program I would make the menus a dictionary, and the menu items would be items in the dictionary. I use the menu item description as the dictionary key. I use the menu item prices as the dictionary value. The menu dictionary lets me use the key (description) to get the value (price). Like menu items are grouped by putting them in the same dictionary. This is a dictionary of all the main meal items.

main_meals = {
    "kids schnitti": 7.99,
    "mini chicken burger": 6.00,
    ".mini beef burger": 6.00,
    "spaghetti": 8.00,
    "lasagne": 7.50,
}

Now if I want to know the price of lasagne I can ask the menu.

print(main_meals["lasagne")

Output:
7.5

I could make a similar menu for drinks.

drinks = {
    "Juice Oringe": 3.00,
    "Juice apple": 3.00,
    "Juice black current": 3.00,
    "milkshake chocolate": 4.50,
    "milkshake strawberry": 4.50,
    "milkshake vanilla": 4.50,
    "milkshake caramel": 4.50,
}

Notice that the main_meals menu have the same structure. They also offer the same functions for working with the menu. Since the main meal and drinks menus work work the same way, I can write code that works with menus, not specific menus. I write a function that takes an order using the GENERIC idea of a menu, not a particular menu. This is abstraction.

def take_order(menu, name=None):
    """Take order from user.
    menu : dictionary of items you can order
    category : What type of items are in menu.  Optional

    returns selected item and item price
    """
    print()
    if name:
        print(name)

    choices = {}
    for index, item in enumerate(menu):
        index = str(index + 1)
        choices.update({index: item})
        price_str = f"${menu[item]:.2f}"
        print(f"{index:>2} {item:{20}} {price_str:>8}")

    choice = input("Enter the number of your choice ")
    item = choices[choice]
    price = menu[item]
    return item, price

print(take_order(drinks, "Drinks")

Output:
Drinks
 1 Juice Oringe            $3.00
 2 Juice apple             $3.00
 3 Juice black current     $3.00
 4 milkshake chocolate     $4.50
 5 milkshake strawberry    $4.50
 6 milkshake vanilla       $4.50
 7 milkshake caramel       $4.50
Enter the number of your choice 4
('milkshake chocolate', 4.5)

I can reuse this function to take your meal order or your drink order or you desert order or any order that is associated with a menu.

This is an old thread that has been bumped with a "thanks" for some reason.
Don't expect to get a response from the OP

[deanhystad]

I think Estherbarnes is a robot. Most responses are very vague. Should have checked the date. Duh!
