Learn How to Work with Numbers and Strings by Implementing the Luhn Algorithm - Step 33

Tell us what’s happening:

Although my code runs fine I am unable to complete the task…
Another question of mine is why I wasn’t able to use

if total == 0:
    print('VALID!')

Thanks in advance, Jonas

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]

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

    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)
        sum_of_even_digits += number
    total = sum_of_odd_digits + sum_of_even_digits
    print(total)

    return total % 10 == 0
def main():
    card_number = '4111-1111-4555-1142'
    card_translation = str.maketrans({'-': '', ' ': ''})
    translated_card_number = card_number.translate(card_translation)

    if verify_card_number(translated_card_number) == 0: #I thought that if x== 0; x = true
        print('VALID!')
    else: 
        print('INVALID!')

here u don’t need to use ==0 because in return from verify_card_number it already returns true or false

this returns true or false
