440 Pointswhy does my if else statement not work?
why is
confirm = input("do you want to proced? Y/N ")
in a loop even if one these perameters are met?
if confirm == "y":
print("SOLD!")
tickets_remaining -= number_of_tickets
elif confirm == "n":
sys.exit("thanks anyways {}!".format(name))
thanks in advance!
import sys
TICKET_PRICE = 10
tickets_remaining = 100
print("there are {} tickets left".format(tickets_remaining))
name = input("what is your name? ")
number_of_tickets = int(input("how much tickets would you like, {}? ".format(name)))
amount_due = number_of_tickets * 10
print("that would be ${}, {}.".format(amount_due, name))
print("are you sure you want to go through with this? ")
confirm = input("do you want to proced? Y/N ")
while confirm.lower != ("y", "n"):
print("whoops! try again!")
confirm = input("do you want to proced? Y/N ")
if confirm == "y":
print("SOLD!")
tickets_remaining -= number_of_tickets
elif confirm == "n":
sys.exit("thanks anyways {}!".format(name))
```

Treehouse Moderator 68,441 PointsHey Sabeen Azhar, there a a few problems with your while
loop conditional
-
confirm.lower
is a bound method. Without specifying the () parens to call the function, this is a reference to the executable itself. - comparing to a tuple
("y", "n")
will only match another tuple of the same values.
You can use the in
operator to see if something is "in" a container of values, such as a tuple:
while confirm.lower() not in ("y", "n"):
Post back if you need more help. Good luck!!
