Tell us what’s happening:

I am getting an indentation error, but it looks indented correctly to me

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 odd_digts:
            print(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()

You don’t need to indent the for line after the odd_digits line, only after the if line to show what is part of the for body

Also take note of the variable name odd_digits
