Describe your issue in detail here.
This step has consistently failed to pass even when I have done as instructed in the hint. I have tried indenting the print(number) statement in and out of the if statement but it is still not working. Kindly help in figuring out what the problem is.
Your code so far
sum_of_even_digits = 0
even_digits = card_number_reversed[1::2]
for digit in even_digits:
number = int(digit) * 2
if number >= 10:
number = (number // 10) + (number % 10)
print(number)
def verify_card_number(card_number):
sum_of_odd_digits = 0
card_number_reversed = card_number[::-1]
odd_digits = card_number_reversed[::2]
for digit in odd_digits:
sum_of_odd_digits += int(digit)
