It's close. I think you're overthinking it. Take it step by step. Decode, process, encode. That means convert the inputs to integers, add the integers, convert the result back. def add(c1, c2): % Decode c1 = ord(c1) - 65 c2 = ord(c2) - 65 % Process i1 = (c1 + c2) % 26 % Encode return chr(i1+65) Or, as a one-liner: A = ord('A') def add(c1, c2): return chr((ord(c1)-A + ord(c2)-A) % 26 + A) -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. -- https://mail.python.org/mailman/listinfo/python-list
