im kinda stuck on this last part

final result should be like thsi:

im stuck on this here:

[glacial pumice]

First the trivial. This:

    print(f'{Qty.} {Item}       {Unit}  {Price}  {Subtotal}')

should probably just be:

    print('Qty. Item       Unit  Price  Subtotal')

A format string (aka an f-string), the f'.....' string syntax, _replaces the {......} bits with the value of the expression inside them. For this heading you just want to print the heading.

[twilit pike]

ok

[glacial pumice]

It should like you need to have gathered a choices variable representing what the customer ordered. Probably a dict whose keys are the menu item key and whose values are the quantity.
I think you should be constructing that in the order_menu() function and having that function return it. So eg in that function put:

    choices = {} # empty dict - nothing yet ordered

and at the bottom:

     return choices

and the bits in the middle should add an entry to the choices ict when an order is entered.

Then you can call it as:

choices = order_menu()

and that gets you the order, which you can pass to print_receipt as the first parameter (i.e. order inside that function).

[glacial pumice]

Then your for-loop in the receipt function can iterate over the order:

for food, quantity in order.items():

The .items() produces (food,quantity) 2-tuples from the order, and the for then unpacks those into the food, quantity variables. Which you then use inside the loop to print that row of the order in the receipt.

I'd start with just printing the values for the receipt rows first - the quantity, the food item, and calculated prices.
Then pretty up the alignment later, after those numbers are correct.

[twilit pike]

i use .get(key,0) to add my order into the dictionary?

[glacial pumice]

Oh, in case that food item key is already there?

Like ordering baguettes, and then again baguettes?

[twilit pike]

yes

[glacial pumice]

Yeah, you could go:

choices[key] = choices.get(key,0) + quanity

[twilit pike]

likes this?

if choice in menu:
            number=int(input("How many croissant would youn like?"))
            price=menu[choice]*number+price
            choices[key]=choices.get(key,0)+number
            print(f'Total so far {price:.2f}')

[glacial pumice]

Looks ok to me.

    print(f'Your total is ${total:.2f}')

the print_receipt function is still not printing idk why

[wild perch]

where exactly does the program 'stop'

uh you have two posts #1435821183084920923 ?

[twilit pike]

yes

[twilit pike]

yes cuz this was an old post so i thought people would forget it

[wild perch]

up till which line in your code does it stop/not work? i can't seem to connect it with the image

[twilit pike]

the print_receipt function stopped working

[wild perch]

well you have to call print_receipt for it to execute the function, just like u calling order_menu

[twilit pike]

ok i did that, but choices is undefined

somehow

[wild perch]

you did this right order,total=order_menu()?

[twilit pike]

no

what does it do?

[wild perch]

you did...

[wild perch]

def print_receipt(order: dict, total: float):
    subtotal=0.0
    total=0.0
    order,total=order_menu() # This line here
    menu={"baguette":4.75,"croissant":2.95,"chocolatine":3.30}
    print("You ordered:")
    print('{Qty.}{Item:5s}{Unit:20s}{Price:25s}{Subtotal:31s}')
    for food,quantity in choices.items():
        stuff=menu[food]
        subtotal=stuff*quantity
        print(f' {quantity}{food}${stuff:.2f}${subtotal:.2f}')
    print(f'Your total is ${total:.2f}')

[twilit pike]

but it still isnt working

[wild perch]

def order_menu():
    choices={}
    price=0.0
    menu={"baguette":4.75,"croissant":2.95,"chocolatine":3.30}
    while True:
        choice=input("What would you like to order (enter Q to quit):").lower()
        if choice=="q":
            break
        if choice in menu:
            number=int(input(f'How many {choice} would you like?'))
            price=menu[choice]*number+price
            choices[choice]=choices.get(choice,0)+number
            print(f'Total so far {price:.2f}')
    return choices, price # here you are returning two values, the name of the values won't carry over when u call a function

order, total = order_menu() # 'order' is the 'choices' and 'total' is the 'price'

# Since the name of the variable you return does not carry over
# This also works and is the same thing:
food, bill = order_menu()

[twilit pike]

now i have unhashable

what does it mean

[digital oar]

can you show what your code looks like now? seems like it's gone over a lot of iterations

menu[order] <--- in here, order is a dictionary, which is not "hashable" and therefore can't be used as a key for another dictionary

The general rule is only immutable things are hashable, like numbers, strings, or tuples (if their contents can't change)
