says tickets sold out when there is tickets

Everything in my code is running perfectly it's just when you for example buy 3 tickets with 100 tickets still remaining it says Sorry the tickets are all sold out!!! :(
There are 97 tickets remaining. the same thing happens when you do not answer "y" , It says Thank you anyways,
Sorry the tickets are all sold out!!! :(

My Code: TICKET_PRICE = 10

tickets_remaining = 100

Run this code continuously until we run out of tickets

while tickets_remaining >=1:

#Output how many tickets are remaining using the tickets_remaininng variable

print("There are {} tickets remaining.".format(tickets_remaining))

#Gather the user's name and assign it to the new variable
User_name = input("What is your name?   ")

#prompt the user by name and ask how many  tickets they would like
num_tickets = input("How many tickets would you like, {}? ".format(User_name))
num_tickets=int(num_tickets)

# Calculate the price (number of tickets multiplied by the price) and  assign it to a variable


Amount_due=num_tickets*TICKET_PRICE

# Output to the price to the screen
print("The total due is ${}".format(Amount_due))
#Prompt user if they want to proceed. Y/N?
proceed = input("Do you want to proceed with your purchase? Y/N")

# If they want to proceed
if proceed.lower()=="y":
    #print out to the screen "SOLD!" to confirm purchase
    # TODO: Gather credit information and process it.
     print("SOLD!")
    # and then decrement the tickets remaining by the number of tickets purchased
     tickets_remaining -= num_tickets
#Otherwise....
else:
    # Thank them by name
    print("Thank you anyways,{}!".format(User_name))

# Notify user that the tickets are sold out
print("Sorry the tickets are all sold out!!!  :(")

that's because your print function on the last line is indented in such a way that it is commanded to print that statement anyway.

add it like this : on the first section:

if tickets_remaining > 0: input(proceed input) elif tickets_remaining == 0 : print("sorry we have sold out")

adding this to the first phase should help your code run in a way it checks first before taking in all the input.

if youre still not sure please let me know, I will be more than happy to elaborate more

assuming that your code begins from " TICKET_PRICE = 10 ". I think you need to intend all the code from 

#Output how many tickets are remaining using the tickets_remaininng variable

print("There are {} tickets remaining.".format(tickets_remaining))

to 

else:
    # Thank them by name
    print("Thank you anyways,{}!".format(User_name))

here is my code, and it works fine:

TICKET_PRICE = 10

tickets_remaining = 100  

# run this code continuously until we run out of tickets
while tickets_remaining >= 1:
    # output how many tickets are remaing using the tickets_remaining varible
    print("there are {} tickets remaining".format(tickets_remaining))

    # Gather the user's name and assign it to a new variable
    name = input("what is your name?: ")

    # prompt the user by name and ask how many tickets they would like
    num_tickets = input("how many tickets would you like?, {} ".format(name))
    num_tickets = int(num_tickets)

    # calcultate the price (number of tickets multiplied by the price) and assign it to a variable
    amount_due = num_tickets * TICKET_PRICE

    # output the price to the screen
    print(" the total is {}".format(amount_due))

    # prompt user if they want to proceed. Y/N?
    should_proceed = input("Do you want to proceed?: Y/N ")


    # if they want to proceed
    if should_proceed.lower()=="y":
        # print out to the screen "SOLD!" to confirm purchase
        # TODO: gather credit card information and process it,
        print("SOLD!")

        # and then decrement the tickets remaining by the number of tickets remaining
        tickets_remaining -= num_tickets

    # otherwise...
        #thank them by name
        print("thank you {}".format(name))


# notify the user that the tickets are sold out
print("the tickets are sold out!")
