The 'if' statement is not showing up when the program is run

If they want to proceed

if should_proceed.lower() == 'y':
    #print out to screen,SOLD to confirm purcahse
    print('SOLD! Your transaction has been approved.')
    #ENter credit card 
    #then decrease the tickets remaining by number of tickets purchased
    tickets_remaining -= num_tickets

this is what my code looks like and for some reason the if statement isn't running

TICKET_PRICE = 10

tickets_remaining = 100

Output how many ticets are left using tickets_remaining variable

print('There are {} tickets remaining.'.format(tickets_remaining))

Get users name and assign to new variable

name = input('What is your name? ')

Prompt user by name, ask how many tickets they want

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

Calculate the price (number of tickets wanted * price of one ticket(10))

cost = num_tickets * TICKET_PRICE

Output price to the screen

print('Total due is £{}.'.format(cost))

prompt user if they want to proceed

should_proceed = input('Would you like to proceed? Yes or No. ')

If they want to proceed

if should_proceed.lower() == 'Y':

#print out to screen,SOLD to confirm purcahse
print('SOLD! Your transaction has been approved.')
#ENter credit card 
#then decrease the tickets remaining by number of tickets purchased
tickets_remaining -= num_tickets
print('There are {} remaining.'.format(tickets_left))

otherwise...

else: #THank yhem by name print('Thank you {}.'.format(name))

print('There are {} remaining.'.format(tickets_left))

This should be

print('There are {} remaining.'.format(tickets_remaining))

Also

if should_proceed.lower() == 'Y':

You should have a lowercase 'y' as you've called .lower()

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

After these changes and correct indenting your code should work fine.

TICKET_PRICE = 10

tickets_remaining = 100

print('There are {} tickets remaining.'.format(tickets_remaining))

name = input('What is your name? ')

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

cost = num_tickets * TICKET_PRICE

print('Total due is £{}.'.format(cost))

should_proceed = input('Would you like to proceed? Yes or No (Y/N). ')

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

    #print out to screen 'SOLD' to confirm purcahse
    print('SOLD! Your transaction has been approved.')
    #Enter credit card
    #Then decrease the tickets remaining by number of tickets purchased
    tickets_remaining -= num_tickets
    print('There are {} remaining.'.format(tickets_left))

else: #Thank them by name
    print('Thank you {}.'.format(name))

Could you post your full code?

I can't see why this wouldn't work, perhaps something before is causing the issue?
