Can you please help me?
I really hope you can help!
I need to create a program where the user can order any combination and
quantity of 3 products. I then offer a 10% discount if the customer correctly
answers a trivia question. After that, there are 3 choices for shipping.
I have most of the program completed but I'm struggling with the most important
parts :/ I get the total of multiple orders of the same item, but we can't
figure out how to total the entire order - before discounts and shipping - and
then where to put any code referring back to the trivia question. Can somebody
please help me with this? I would really appreciate it!
This is the code:
shop_again = 'y'
print("Welcome to the Star Wars Shop!")
customer = eval(input("Is there a customer in line? (1 = yes, 2 = no)> "))
while shop_again == 'y':
if (customer == 2):
print("Welcome to the Star Wars Memorabilia Shop!")
customer = eval(input("Is there a customer in line? (1 = yes, 2 = no)>
"))
elif (customer == 1):
print("Please select an item to update your order and any other number
to check out.")
print("Yoda Figure: $10 each.")
print("Star Wars Movie DVD: $20 each.")
print("Death Star Lego Set: $200 each.")
print(" 1 for Yoda Figure")
print(" 2 for Star Wars Movie DVD")
print(" 3 for Death Star Lego Set")
order = eval(input("Order: "))
if (order == 1):
yoda = eval(input("How many Yoda Figures do you want? : "))
total = 10 * yoda
print("Total:", total)
print("Current order:", yoda, "at", total)
if (order == 2):
movie = eval(input("How many Star Wars Movie DVDs do you want? : "))
total = 20 * movie
print("Total:", total)
print("Current order:", movie, "at", total)
if (order == 3):
legos = eval(input("How many Death Star Lego Sets do you want? : "))
total = 200 * legos
print("Total:", total)
print("Current order:", legos, "at", total)
shop_again = input("Would you like to keep shopping? 'Y' for yes, 'N' for
no: ")
print()
print("Your order before shipping and discounts: ",total)
print()
print("Answer a trivia question for a discount!")
discount = eval(input("On what planet did Yoda live when Luke Skywalker first
met him? 1) Earth 2) Dagobah 3) Pluto :"))
if (discount == 1):
print("Sorry, that answer was wrong!")
if (discount == 2):
print("That's correct, you get a 10% discount!")
if (discount == 3):
print("Sorry, that answer was wrong!")
print()
if (discount == 2):
(total * .9)
print("Your total before shipping: ",total)
print("1) Regular Shipping: 3-4 business days, $5.00 per $50 ordered. 2)
Express Shipping: overnight, $10 per $50 ordered. 3) Super Saver Shipping: 7-10
business days, free.")
shipping = eval(input("Please select the shipping method you want: "))
if (shipping == 1):
total == total % 50
total == total * 5
print("Your total is: ",total)
if (shipping == 2):
total == total/50
total == total % 50
total == total * 10
print("Your total is: ",total)
if(shipping == 3):
print("Your total is: ",total)
print()
print("Thanks for shopping here! Please come again!")

Re: Can you please help me?
Thank you very much for your reply. I actually just deleted this post as you were replying! I had figured out a few things and then got confused about a few others :/ If you have a chance, can you look at the other post? Thank you!! -- http://mail.python.org/mailman/listinfo/python-list
Re: Please help if you can!
First, sorry for starting a new post - I didn't want anyone to have to read through the whole first one when the questions were completely different :/ Second, I honestly have no idea how to answer your questions. I am a sophomore in high school and I am trying to learn this on my own because my teacher is not very good at explaining things. i just cant figure out how to get the total when an order is placed without the customer ordering at least one of each item. I also can't figure out how to get the shipping to calculate correctly. It is an intro class and we are using just the basics. Most of what Mitya said is stuff I've never seen before, although I am very grateful for her response, I am supposed to use only what the teacher "taught". Sorry if I frustrated you. I'm just a kid trying to learn.

Re: Please help if you can!
I cannot tell you how grateful I am that you took the time to do all of this.
I have been working on it all day and you are a better teacher in a few minutes
than my teacher has been in 4 months. THANK YOU!
And thank you again, Mitya. I really appreciate your time and effort too!
Someday I'll be advanced enough to understand it lol
I'm going to take a break and work on it more tomorrow. I'll be back.
Thank you!
