Can anyone help me understand why I cannot update the remaining tickets?

Can anyone help me understand why I cannot update the remaining tickets? It keeps outputting 100 tickets even after I input I want to purchase 100 tickets.

""" To-Do

1) As a User, I should have a personalized experience so that I feel welcomed by the brand.

2) As a User, I should have errors reported in a user-friendly manner

3) As a User, I should be able to request a certain amount of tickets and be told the total cost, so that I can determine if I want to purchase the tickets

4) As a result, I should be able to confirm my order, so that I do not accidentally purchase more tickets than intended

5)As a User, I should not be offered tickets if there aren't any available

6) As a User, I should be shown the number of tickets left remaining, so I can understand the importance of buying now. """

TICKET_PRICE = 10

ticket_remaining = 100

Run this code continuously until we run of tickets

while ticket_remaining >= 1: # Line 26 goes over the amount of tickets remaining - To-Do #6 print("There are {} tickets remaining.".format(ticket_remaining))

# Gather the user's name and assign it to a new variable - To-Do #1
CustomerName = input("Welcome to Ticket Master, lets start with your name. What is your name? ")

CustomerTicketRequest = input("Thank you {} for choosing Ticket Master, how many tickets would you like to "
                              "purchase? ".format(CustomerName))
CustomerTicketRequest = int(CustomerTicketRequest)

# Calculate the price (Number of tickets multiplied by the price) and assign it to a variable. Output the price -
# To-Do #3

TicketCalculation = int(CustomerTicketRequest * TICKET_PRICE)
print("Your total ticket cost is ${}".format(TicketCalculation))

# Prompt user if they want to proceed. Y/N? To-Do #4,
# If "Yes" print out a message saying "Sold!" To confirm purchase, and then decrease the amount of tickets available
# If "No" Thank them by name

CustomerConfirmation = str(input("If you would like to continue with your purchase, type 'yes' or 'no'. ")).lower()

if CustomerConfirmation != "yes":
    print("Thank you for choosing Ticket Master, your purchased ticket cost is ${}".format(TicketCalculation))
    ticket_remaining -= CustomerTicketRequest

else:
    print("Thank you for choosing Ticket Master {}, please come again".format(CustomerName))

Notify the user that the tickets are sold out

print("Thank you for choosing Ticket Master but we are sold out.")

I resolved the issue:

if CustomerConfirmation != "yes":

I was using !=, which is meant to be used for inequalities; switching it to == (equality) works like a champ!
