So a user can currently put anything in the confirm purchase except N or n. How to change?

Currently when confirming as long as the user does not put N/n in as input, the program confirms the order.

How would I and where would I add code that says it needs to be Y/y/YES/yes. or even something like if not Yes or no related it makes the user try again?

I'm not seeing the same thing you are. In the video's workspace the confirmation checks for "y" or "Y" (by converting the variable storing the input to lowercase) on line 23:

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

If you also wanted to include various combinations of case for "yes" you could add

if should_proceed.lower() == "y" or should_proceed.lower() == "yes":

Can you provide a link/time for the video showing the code checking for N/n?

Hi,

I am a beginner to python so I don't know if this the ideal solution... but I tried this using "else if" (elif) to see if could get this to work:

 if confirmation.lower() == "yes":
        tickets_remaining -= number_of_tickets
        print("Thanks, {}! Your tickets are confirmed! There are now {} tickets remaining".format(customer_name, tickets_remaining))
    elif confirmation.lower() == "no":
        print("No problem, {}. No purchase has been made".format(customer_name))
    else:
        print("Please enter a valid answer. Your order has not gone through") ```
