Hi people!! I'm trying to solve the kaleidoscopes coding challenge. Can someone pls tell me what's wrong with my code?

Question

num = int(input())
if num>1:
num = num - 0.1*num
total cost = 5*num + 0.07*num
print (float(total cost))

Answer 1

Rainnn ,

additional to the incorrect naming of the variable, 2 other issues has to fixed:

> the discount is currently calculated from the >number of items<. this is not correct. it should be calculated from the
costs of >number of items * price<

> the final output has to be >rounded to 2 decimal places<. currently a float conversion is used. this has to be corrected.

Answer 2

Spaces are not used in variables creation.
total cost invalid
check again tax calculations. Should be counted on total. not on num value...

Answer 3

You forget to put _ between total_cost
Python don't accept spaces in variables.
That the function code:

num = int(input())
if num>1:
num = num - 0.1*num
total_cost = 5*num + 0.07*num
print (float(total_cost))

Answer 4

Rainnn ,

use round(...)

Answer 5

Rainnn ,

read my comments and rework the code.

Answer 6

print(round(total_cost,2)) # here 2 means 2 decimal places.

Answer 7

I solved it! Thanks so much for all the help!!

Answer 8

Can someone pls tell me what to do after this? Thanks!!

Answer 9

how do I round to 2 decimal places?
