I encountered a weird bug in one of the checks for this puzzle.
For the array [-37,-36,-19,-99,29,20,3,-7,-64,84,36,62,26,-76,55,-24,84,49,-65,41] my function threw an AssertionError, although all other checks went fine. After some digging, I found that something is wrong with the indexes that Python returns. There is a 9 where the index 16 should be.
... Element index: 14 Element value: 55
Element index: 15 Element value: -24
Element index: 9 Element value: 84
Element index: 17 Element value: 49
Element index: 18 Element value: -65 ...
The code I used was:
def checkio(array): """ sums even-indexes elements and multiply at the last """ for element in array: print("Element index:", array.index(element)) print("Element value:", element, "\n") try: summe = sum({element for element in array if array.index(element) % 2 == 0}) return summe*array[-1] except IndexError: return 0 #These "asserts" using only for self-checking and not necessary for auto-testing if __name__ == '__main__': assert checkio([-37,-36,-19,-99,29,20,3,-7,-64,84,36,62,26,-76,55,-24,84,49,-65,41]) == 1968, "41*(-37-19+29+3-64+36+26+55+84-65)"
I would be interested to hear what caused this strange behavior.
Thank you so much.
