Python Python Basics All Together Now Branch and Loop

Stuck in a loop.

Hi. My script for some reason seem to be stuck in a loop. I tried to add break to the end of it but I got break outside loop error. What can I do to fix it?

I ask for 56 tickets first. Receive 44 ticket left. During the second run I ask for 44 tickets but get 56 tickets left instead.

TICKET_PRICE = 10

tickets_remaining = 100


while tickets_remaining >= 1:


    name = input('What is your name?   ')
    print(f'Welcome {name}')


    buy_tickets = int(input(f'How many tickets do you want {name}?  '))
    total_cost = buy_tickets * TICKET_PRICE
    print(f'Total cost is {total_cost} $')

    ask = input('Would you like to proceed? Y/N   ')
    if ask.lower() == 'y':
        print(f'Order received. {buy_tickets} ticket reserved.')
        r_tickets = tickets_remaining - buy_tickets
        print(f'{r_tickets} tickets left.')

    else:
        print(f'Thank you for considering us {name}.')

print('Sorry the tickets are all sold out.')

The "tickets_remaining" is not being updated in this code, so every transaction will draw from the original 100.

So instead of creating a new total like this:

        r_tickets = tickets_remaining - buy_tickets
        print(f'{r_tickets} tickets left.')

You could update the count of remaining tickets instead:

        tickets_remaining -= buy_tickets
        print(f'{tickets_remaining} tickets left.')
