Tell us what’s happening:

I can’t quite work out what I’ve done wrong here.

Your code so far

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


# User Editable Region

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

# 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):
        print(sum_of_odd_digits)

main()
