Describe your issue in detail here.

Hello, I think my error is in the numbers for card_number[0:4]. I tried inputting different numbers such as [0:4:4] and many others, but it still gives me an error.


# User Editable Region

  def verify_card_number(card_number):
    sum_of_odd_digits = 0
 card_number_reversed = card_number[0:4]

# User Editable Region

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

    print(translated_card_number)

    verify_card_number(translated_card_number)

main()

Thanks a lot. It’s a intro python error that I didn’t think about and I messed the code while trying to fix it.
