Question

cart = [15, 42, 120, 9, 5,380]
discount = int(input())
total = 0
for y in cart:
total = y - (y*discount/100)
total += total;
Print (total)

Answer 1

total += total means total = total + total = 2 * total which is wrong and gives wrong output

Answer 2

Virendra Agarkar

Ok then if you want to use loop and calculate individual discount then do this:

cart = [15, 42, 120, 9, 5, 380]

discount = int(input())
total = 0

for y in cart:
total += y - y * discount / 100

print (total)

Answer 3

Why we have to use '+=' in code not 'total += total'

Answer 4

Thanks i got it

Answer 5

Why did you do 2 times -y?

Answer 6

Virendra Agarkar

First get total from the list cart then get discounted amount from total using this formula.

Y - (Y*X/100) where Y = total, X = discount

Answer 7

How?

Like this using sum function get total then calculate discount.

cart = [15, 42, 120, 9, 5, 380]

discount = int(input())
total = sum(cart)

print(total - total * discount / 100)

Answer 9

But we have to take total of each element discount and then take total it.

Answer 10

You’re making a shopping cart program.

The shopping cart is declared as a list of prices, and you need to add functionality to apply a discount and output the total price.

Take the discount percentage as input, calculate and output the total price for the shopping cart.

Answer 11

Use a for loop to iterate over the list.
Use the following formula to calculate the result of X% discount on $Y price: Y - (Y*X/100)

Answer 12

Virendra Agarkar

Instead of taking individual discount and then add them we can add all amount then get discount, both will give same result.

Answer 13

But how to do it i am unable to write perfect code

Answer 14

cart = [15, 42, 120, 9, 5, 380]

discount = int(input())
total = 0
i=0
for x in cart:
total = total+(cart[i] - (cart[i]*discount/100))
i=i+1
print(total)
