My tickets remaining stays at 100

Heres my code

TICKET_PRICE = 10

user_name = input("What is your name? ")

tickets_remaining = 100

while tickets_remaining >= 1:

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

ticket_amount = input("Howmany tickets would you like?  ")
ticket_amount = int(ticket_amount)
ticket_price_total = (TICKET_PRICE * ticket_amount)
print("The total price is {}".format(ticket_price_total))

proceed_ans = input("Would you like to proceed? Y/N?  ")

if proceed_ans.lower == "y":
    print("sold!")

tickets_remaining = (tickets_remaining - ticket_amount)
else:
          print("bummer, {}".format(user_name))

print("Thanks for shopping {}".format(user_name))

print("Sorry, we're out of tickets")

lower needs to be followed by parentheses here:

if proceed_ans.lower() == "y":

Also I am assuming you are indenting properly. I can't tell based on how your post is formatted.

Here is mine Workspace: https://w.trhou.se/doz1vwq3eh

What I fail to understand is the global scope to local scope. How do I update the variable remaining_tickets. I was thinking that I should just return from my function remaining_tickets, but that did not work.

when you are subtracting the tickets remaining comes before the number of tickets. EX tickets_remaining -= num_tickets
