code only working in treehouse workspace?

It worries me that this code works fine in the treehouse workspace, but if you try it in atom and terminal proper, it returns 'NameError" when attempting to take the user name, and take the answer to "would you like to proceed?"

Hi! I ran the code locally and had no problems. You can post your code here so we can take a look and see if there's a mistake causing the error.

HI Megan, thanks for the reply. Here's my code - working fine in treehouse, but still no in terminal.

''''tickets_remaining = 100 TICKET_PRICE = 10

while tickets_remaining >= 1 :

name = input("Hello, welcome to ticketmaster. What is your name? ")

tickets = input("How many tickets would you like, {}? ".format(name))

try:

tickets = int(tickets)

if tickets > tickets_remaining :
  print("Sorry, there is only {} tickets remaining".format(tickets_remaining))
  quit()

except ValueError as err: print("Sorry, try again {}".format(err))

else:

owed = TICKET_PRICE * tickets
amount_of_tickets = tickets_remaining - tickets

print("That will be {} dollars".format(owed))
should_proceed = input("Do you want to proceed?    Y/N    ")

if should_proceed == "n" :
    print("Thanks Anyway")
    quit()
else:
    print("SOLD, Thanks!")
    tickets_remaining = amount_of_tickets
    print("There are {} tickets remaining".format(amount_of_tickets))

print("Tickets are sold out, sorry")'''

I ran this locally and everything worked just fine. Have you tried a different IDE in case it's a setting in Atom?

tickets_remaining = 100 
TICKET_PRICE = 10

while tickets_remaining >= 1 :
    name = input("Hello, welcome to ticketmaster. What is your name? ")
    tickets = input("How many tickets would you like, {}? ".format(name))
    try:
        tickets = int(tickets)
        if tickets > tickets_remaining :
            print("Sorry, there is only {} tickets remaining".format(tickets_remaining))
            quit()
    except ValueError as err: 
        print("Sorry, try again {}".format(err))
    else:
        owed = TICKET_PRICE * tickets
        amount_of_tickets = tickets_remaining - tickets
        print("That will be {} dollars".format(owed))
        should_proceed = input("Do you want to proceed?    Y/N    ")
        if should_proceed == "n" :
            print("Thanks Anyway")
            quit()
        else:
            print("SOLD, Thanks!")
            tickets_remaining = amount_of_tickets
            print("There are {} tickets remaining".format(amount_of_tickets))

print("Tickets are sold out, sorry")
