Help me write Python code for giving discount to product A, B, C with different price per unit

Question

For example, product A is 30 dollars per unit. If one buys between 1 to 99 of product A, no discount. If from 100 to 199, 3% discount etc.
For product B, product is $50 per unit with same discount as above.
Product C is $100 per unit with same discount as above.
Print the final account paying with discount given

Answer 1

Code by: MUHAMMED TAHIR MUHAMMED

x = "DISCOUNT CALCULATION"
var1 = 4
print("MY {} ASSIGNMENT FOR QUESTION {}".format(x,var1))

product_code = str(input("Enter Product code:"))
number_unit = int(input("Enter the number of unit:"))

print("You have ordered for product {}, with price {}".format(product_code,number_unit))

#Product code / Set price of product
if product_code == "A":
price = 30
elif product_code == "B":
price = 50
elif product_code == "C":
price = 100

#Set discounts
if 1 <= number_unit < 100:
discount = 0
elif 100 <= number_unit < 500:
discount = 0.01
elif number_unit > 500:
discount = 0.25
else:
discount = 0.2

#Create function
def total_price(cost, disc, num):
disc_price = cost - (cost*disc)
final_price = disc_price * num
return final_price

#Call the function
print(total_price(price, discount, number_unit))

Hye MUHAMMED TAHIR MUHAMMED

Can you please share your code attempt?

Btw 《 Nicko12 》 how do you know that he is talking about that code only?

One more thing it would be pleasure if you can put the code in "a code"

Answer 3

First show your attempt here

Answer 4

I thought of using nested if-else statements but you can shorten it like using def function etc. if you want cleaner code.

if (product_code=="A"):
if 1<=number_unit <100:
discount = 0
elif 100 <= number_unit < 500:
discount = 0.01
elif number_unit > 500:
discount = 0.25
else:
discount = 0.2
amount_discounted = discount * 30
price=number_unit*30
final_price = price - amount_discounted

elif (product_code=="B"):
if 1<=number_unit <100:
discount = 0
elif 100 <= number_unit < 500:
discount = 0.01
elif number_unit > 500:
discount = 0.25
else:
discount = 0.2
amount_discounted = discount * 50
price=number_unit*50
final_price = price - amount_discounted

elif (product_code=="C"):
if 1<=number_unit <100:
discount = 0
elif 100 <= number_unit < 500:
discount = 0.01
elif number_unit > 500:
discount = 0.25
else:
discount = 0.2
amount_discounted = discount * 100
price=number_unit*100
final_price = price - amount_discounted

Answer 5

I was asking Muhammed Tahir bro, he is the thread starter ...

Answer 6

Ok so I noticed something about this line.
So example a costumer buys Ten $100 product with 30% or 0.30 discount

amount_discounted = discount * 100 #This is equal to $30
price=number_unit*100 #10 * 100 = $1000
final_price = price - amount_discounted # $1000 - 30$ = $970

This should be like this:

price = 100
discounted_price = price - (price*discount) # $100 - ($100*0.30) = $70
final_price = discounted_price *number_unit # $70 * 10 = $700

The second one is correct becuase I get the discounted price of EACH product first, notice how different they are.
If you're still confused. Feel free to ask.

Answer 7

Thanks so much for your efforts and contribution

Ipang I'm really Sorry I did not notice your username.

Answer 9

No problem. I remain greatful

Answer 10

x="DISCOUNT CALCULATION"
var1=4
print("MY {} ASSIGNMENT FOR QUESTION {}".format(x,var1))
product_code=str(input("Enter Product code:"))
number_unit=int(input("Enter the number of unit:"))
print("You have ordered for product {}, with price {}".format(product_code,number_unit))
if (product_code=="A"):
if 1<=number_unit <100:
discount = 0
elif 100 <= number_unit < 500:
discount = 0.01
elif number_unit > 500:
discount = 0.25
else:
discount = 0.2
amount_discounted = discount * 30
price=number_unit*30
final_price = price - amount_discounted

Answer 11

How are you calculating the discount? do you reduce from product price or from subtotal?

Answer 12

Help with those code for product A B and C

Answer 13

Piyush[21 Dec❤️]
Oh, you're right, I did not save and send the final code, it would be much easier for both of us. I'll do it next time.

And I don't think he is talking about the code only that's why I also explained how discount of multiple product works.

Anyway, Thanks!
