Your code so far

    card_number_reversed = card_number[::-1]
    odd_digits = card_number_reversed[::2]

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

Hallo und willkommen in unserer Community!

My German is rudimentary so forgive me for communicating in English…
The first line inside your for loop should be outside the for loop, directly below the sum_of_even_digits declaration.
Also, your print command should be indented four spaces to be inside your for loop.
Finally, as your for loop iterates digit in even_digits, you should be printing each digit, not even_digits.

I hope that helps!
