1,028 PointsWhy is there a type error for the ">" sign?
TICKET_PRICE = 23.99
tickets_remaining = 100
while tickets_remaining >= 1: user_name = input("Please enter your name: ") print("There are {} tickets remaining.".format(tickets_remaining))
amount_purchased = input("How many tickets would you like {}? ".format(user_name))
try:
if amount_purchased > tickets_remaining:
raise ValueError("That is not possible, sorry")
amount_purchased = int(amount_purchased)
except ValueError:
print("That is not a valid value, please enter a number")
else:
total_cost = TICKET_PRICE * amount_purchased
print("your total for this is £{}".format(total_cost))
proceed = input("Do you want to proceed with this sale, PLease enter yes or no: ")
if proceed == "yes":
print("SOLD!!")
tickets_remaining -= amount_purchased
elif proceed == "no":
print("Ok, Thank you anyway!")
else:
print("That is not a valid answer")
print("We are so sorry but we are all out of tickets")
The problem is, I am trying to raise an exception Error but the code stops running after the if statement which says, "amount_purchased > tickets_remaining?

Treehouse TeacherHi there, Faraz Jahangiri ! The problem here is that you cannot compare a string to an integer in this way. The input that the user gives will be of type string. And tickets_remaining
is an integer. To compare them, you will first need to convert the user's input to an int
.
On line 9 try this instead:
# convert the user's input to an integer for comparison
amount_purchased = int(input("How many tickets would you like {}? ".format(user_name)))
Hope this helps!

12,964 PointsHi Faraz Jahangiri! I'd like to help, but your code isn't in proper syntax. While I can correct the syntax in my workspace, I can't be sure that it's set up the same way as yours.
Hope this helps! :)
