2,849 PointsBranch and loop on tickets_remaining exercise
In the while loop, the codes still runs if the num_tickets is zero, is it supposed to run after we already specified it as >=1 ?
TICKET_PRICE = 10
tickets_remaining = 100
Run this code continuosly until we run out of tickets
while tickets_remaining >= 1:
# Output how many tickets are remaining using the tickets_remaining variable.
print("There are {} tickets left".format(tickets_remaining))
# Gather the user's name and assign it to a new variable.
name = input("What is your name? ")
# Prompt the user by name and ask how many tickets they would like.
number_of_tickets = int(input("Hey {}, how many tickets would you like?".format(name)))
# Calculate the price(number of tickets multiplied by the ticket_price) and assign it to variable
price = number_of_tickets * TICKET_PRICE
# Output the price to the screen
print("The ticket costs ${}".format(price))
# Prompt user if they want to proceed Y/N?
should_proceed = input("Do you want to proceed? Y/N ".format(name))
# if they want to proceed
if should_proceed.lower() == "y":
# print out to the screen SOLD! to confirm purchase
print("SOLD!")
# and the decreament of the tickets remaining by the number of tickets purchased
tickets_remaining -= number_of_tickets
# Otherwise....
else:
# Thank them by name
print("Thank you {} for patronizing us".format(name))
Notify the user that tickets are sold out
print("Hey {} the tickets are sold out".format(name))

2,364 PointsHey Temi,
Looking over your code, I noticed you did not add a couple of items. I am pasting your code and including the item that I am referring to, as well as commenting on them with my name next to it.
TICKET_PRICE = 10 tickets_remaining = 100
To trigger the remaining tickets available, you need the while loop - Chris Diaz
while tickets_remaining >= 1:
# The code in line 7 outputs the latest number of tickets available - Chris Diaz
print("There are {} tickets remaining".format(tickets_remaining))
# Gather the user's name and assign it to a new variable.
name = input("What is your name? ")
# Prompt the user by name and ask how many tickets they would like.
number_of_tickets = int(input("Hey {}, how many tickets would you like?".format(name)))
# Calculate the price(number of tickets multiplied by the ticket_price) and assign it to variable
price = number_of_tickets * TICKET_PRICE
# Output the price to the screen
print("The ticket costs ${}".format(price))
# Prompt user if they want to proceed Y/N?
should_proceed = input("Do you want to proceed? Y/N ".format(name))
# if they want to proceed
if should_proceed.lower() == "y":
# Print out to the screen SOLD! to confirm purchase
print("SOLD!")
# and the decrement of the tickets remaining by the number of tickets purchased
tickets_remaining -= number_of_tickets
# Otherwise....
else:
# Thank them by name
print("Thank you {} for patronizing us".format(name))
This gets triggered once the application recognizes it no longer has tickets - Chris Diaz
print("Sorry the tickets are all sold out!!!")
