[Tutor] [TUTOR]Code Deciphering
Hi! I was wondering, how do you use Python to decipher codes? It feels like it should be pretty simple, but I haven't found any tutorials about it yet. Have a nice day! // Calle ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Generally speaking, a code represent letters or numbers in transmitting a message. In other words, a code deals with phrases and sentences or whole words. Example "steal the cabbage at dawn" could mean "kill the king on wednesday". A cipher deals with letters. It is a message written in letters in a predetermined code. This means that a cipher is a system of communication that uses letters instead of phrases. Examples being the standard Caesar cipher where "APPLE" might be written "BQQMB" (ie, shifted one letter to the right). -- best regards, Robert S. -- Hi! Sorry, I meant ciphers. How would a basic script for solving move-one-step-to-the-right ciphers look like?

There are different ways to solve that, but show us what you've come up with so far and we might be able to point you in the right direction. You won't learn anything by getting the answer posted and just copy-paste it for whatever (nefarious) use you need it; you'll learn a lot more if you work toward the solution yourself. I'll just point you in the direction of ASCII values for now. -- best regards, Robert S. Well, I don't really know where to begin. I tried looking at other peoples code and write something based on that, but it ended up being too similair to the original code... I could show you what I came up with using pseudo-code. Get the cipher from user. Use ord() to convert into numbers. Add number to a new string while at the same time making it into a letter using chr(). Repeat 25 times and print the results. Am I on the right track with this or should I re-think? // Calle ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
