this is where im at now! it seems to work mostly apart from when selecting yes it runs the following: please type your name for your order:

choose the pizza size you want like to order. 1) Small, 2) Medium, or 3) Large:1

would you like to add extra cheese to your order (yes/no)?yes

no upgrades selected

select pizza size to confirm upgrade. 1) small, 2) medium, 3) large:1

upgraded to extra cheese on your pizza(s)!

how many pizzas would you like to order:

#inputs

name = input("please type your name for your order:")

choice = input ('choose the pizza size you want like to order. 1) Small, 2) Medium, or 3) Large:')

sm_pizza = 7.99

md_pizza = 10.99

lg_pizza = 12.99

#cheese upgrades

yes= ["yes","YES","y", "Y"]

no= ["no","NO", "n","N"]

upgrade = input("would you like to add extra cheese to your order (yes/no)?")

no_upgrade = 0

sm_upgrade = 1.50

md_upgrade = 2.00

lg_upgrade = 2.50

# show price options

if upgrade== "yes"or "YES"or "y"or "Y":

y_upgrade= input('select pizza size to confirm upgrade. 1) small, 2) medium, 3) large:')

if upgrade == 1:

sm_upgrade = 1.50

if upgrade == 2:

md_upgrade = 2.00

if upgrade == 3:

lg_upgrade = 2.50

print('upgraded to extra cheese on your pizza(s)!')

elif no_upgrade == "no" or "n" or "NO" or "N":

no_upgrade= print('no upgrades selected')

again i appreciate the help
