works fine in Workspace but not locally?

So I finished the masterticket.py and code works fine on TeamTreehouse's Workspace; however, I copied/pasted the same code onto my local computer (sublime) and I'm getting a NameError: name 'blah' is not defined when I try to run it and input a name.

Any ideas why I'm getting this error locally but not in the workspace??

Could you please share the code alongside or provide the course/lecture related to this question.

From the looks of it, _blah _ is something only defined in workspace environment and is not a globally available variable.

lol blah was an arbitrary example...

name = input("Hello! What's your name? ")

oh!!! I thought...

name = input("Hello! What's your name? ")
print(Blah)

C:\Users\username>python c:/Users/username/Desktop/todel.py
Hello! What's your name? Blah
Traceback (most recent call last):
  File "c:/Users/username/Desktop/todel.py", line 3, in <module>
    print(Blah)
NameError: name 'Blah' is not defined

or something similar.

If the code is...

name = input("Hello! What's your name? ")

This should be running fine in any file.

Here is when i tried the above line in a file...

C:\Users\username>python c:/Users/username/Desktop/todel.py
Hello! What's your name? BlahBlah

C:\Users\username>

You'll need to add more details regarding your problem.

here's the code that runs fine in treehouse's workspace but not locally for me..

SERVICE_CHARGE = 2
TICKET_PRICE = 10
tickets_remaining = 100  


# Create the calculate_price function, It takes number of tickets and retunrs buy_tickets * TICKET_PRICE
def calculate_price(number_of_tickets):
  return (number_of_tickets * TICKET_PRICE) + SERVICE_CHARGE


while tickets_remaining >= 1:
  print("there are {} tickets remaining.".format(tickets_remaining))
  name = input("Hello! What's your name? ")
  buy_tickets = input(("Hi {}! How many tickets would you like to buy? ".format(name)))
  # Expect a ValueError to happen and handle it appropriately...remember to test
  try:
    buy_tickets = int(buy_tickets)
    # Raise a ValueError if the request is for more tickets than are available
    if buy_tickets > tickets_remaining:
      raise ValueError("There are only {} tickets remaining.".format(tickets_remaining))
  except ValueError as err:
    # Include the error text in the output
    print("Oh no, we ran into an issue. {}. Please try again.".format(err)) 
  else: 
    total_cost = calculate_price(buy_tickets)
    print("That will be ${}!".format(total_cost))
    response = input("Would you like to proceed? Y or N? ")
    if response == "Y" or response == "y":
      # TODO: Gather Credit Card Info and process it.
      print("SOLD!")
      tickets_remaining -= buy_tickets
    else:
      print("Thanks {} for stopping by!".format(name))
print("Sorry, all the tickets have been Sold Out")

Although it takes negative number of tickets as input.. but code is executing just fine. I think you'll have to add the error as well.
