Tell us what’s happening:

Could I ask for some help here? I am not too sure what the question is asking as the output of this code is correct. I have some background in coding (MATLAB and C++) so I am just trying to get more familiar with Python syntax but I have no idea what am I doing that is wrong here

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 i in range(len(odd_digits)):
        print(odd_digits[i])
    

# 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()

Hi. You are asked to loop over each digit in odd_digits. and then print each digit. Your code needs some slight adjustment.

Welcome to the community!

In add to a1legalfreelance’ tip:
Here you’ll find a fine example of how much simpler and more abstracted Python is, compared to C/C+.

Best reset the solution and take the instructions by word, literally just use the expressions in the text for the if condition.

Best Regards
