Question

How do i fix this why is TestCase #3,4 and 7 is wrong

cost = input().split(",")
cost = [float(x) for x in cost]
cost.remove(max(cost))
tax = int(sum(cost) * 0.07)
discount = 0
for i in cost:
discount = float(discount)+ (i * 0.3)
savings = tax + discount
print(int(savings))

Answer 1

Adventure of Tol ,

we can simplify the code and also get it run:

cost = input().split(",") # next 3 lines are your code
cost = [float(x) for x in cost]
cost.remove(max(cost))

total_discount = sum(cost) * 1.07 * 0.3 # rework this line -> build the sum of cost, add the tax and calculate the saving

#discount = 0 # next 4 lines are not required
#for i in cost:
# discount = float(discount)+ (i * 0.3)
#savings = discount

print(int(total_discount)) # output the result

Answer 2

Adventure of Tol ,

this way (multiplying by 1.07) we add the required tax of 7% to the sum of the cost. after this step we calculate the discount by multiplying by 0.3.

Answer 3

Where is task description?
Add details pls..

edit: Adventure of Tol Don't round the tax before. round only total savings...

Lothar Thanks brother, but can you enlighten me why the sum(cost) is multiplied to 1.07?
