Tell us what’s happening:

I have tried this several times but still not getting it I need help

Your code so far

# User Editable Region

def verify_card_number(card_number):
    sum_of_odd_digits = 0
    card_number_reversed = card_number[::-1]
    odd_digits = card_number_reversed[::2]

   for digits in odd_digits:
       sum_of_odd_digits += int(digit)
    print(sum_of_odd_digits)
    

# User Editable Region

def main():
    card_number = '4111-1111-4555-1142'
    card_translation = str.maketrans({'-': '', ' ': ''})
    translated_card_number = card_number.translate(card_translation)

    verify_card_number(translated_card_number)

main()

Use a for loop to iterate over each digit in the odd_digits list. Move your print call from the previous step into the for loop, and change it to print each digit.

@Osei17

for digits in odd_digits:
    sum_of_odd_digits += int(digit)
 print(sum_of_odd_digits)

The challenge was not to add anything to sum_of_odd_digits, all you need to do is print your digits ( as you named it ) each time within your loop.
