e above, but you can create it on the fly with a different #value for the shift. You could also use a different alphabet. # def generate_caesar_cipher(alphabet,shift): offset = shift - len(alphabet) cipheralpha = ''.join((alphabet[offset:], alphabet[0:offset])) return dict(zip(alphabet,cipheralpha)) caesar_shift = 3 values = dict() values.update(generate_caesar_cipher(string.ascii_letters,caesar_shift)) One other thing to consider is that you can use the underutilized function 'translate' from the string module. The 'maketrans' function creates a translation table and the 'translate' function applies that to input. def alt_trans(plain_alpha,shift): offset = shift - len(plain_alpha) cipher_alpha = ''.join((plain_alpha[offset:], plain_alpha[0:offset])) return string.maketrans(plain_alpha,cipher_alpha) plaintext = 'Alea iacta est.' shift_cipher = alt_trans(string.ascii_letters, caesar_shift) ciphertext = string.translate(plaintext,shift_cipher) Enjoy Python! -Martin -- Martin A.

Re: [Tutor] Request for advice on Python code

Greetings Elaina, I will echo Alan's remarks--it sounds like you are using a quite specialized (specialised?) module. It is certainly not a module with which I am familiar, not in the standard library, and not a commonly encountered problem. I would classify this module as domain-specific.
