Super sale

Question

Hello guys,

This is my code for the Super Sale problem, some of the output are correct but not all and I don’t know why:

import math

price = input()
price_list = price.split(',')
price_list_int = [int(x) for x in price_list]

highest = 0

for i in price_list_int:
if i >= highest:
highest = i
price_list_int.remove(i)

save = 0.3*sum(price_list_int)

new_price = sum(price_list_int)-save

taxe = 0.07 * save

total_save = math.floor(save+taxe)

print(total_save)

Thanks !

Julien Badii ,

there are 2 issues in thd code:

(1) the list comprehension used is converting the prices to an integer value, so all decimal places get eliminated:
...
price_list_int = [int(x) for x in price_list] # should be float(x) not int(x)
...

(2) the code in the for loop does not necessarily create correct results, since values are removed during iteration cycles:
...
for i in price_list_int: # do not iterate over a list where elements are removed !!!!
if i >= highest:
highest = i
price_list_int.remove(i)
...

to get the highest price removed, we can use max(...) function and remove this from *price_list_int*

>> after applying this modifications, the code should pass all test cases properly.

Is it that you need to floor or round up?
