Basic Encryption in Python

Question

I'm trying to explore some encryption types in python. Could anyone provide me with some beginner encryption code? Thanks for any help. I've already tried changing the length of the message, but that didn't work. Please help!

Hacking Ciphers is a great resource! Here is some example code.

import sys
import cmd




message = cmd.raw_input("Enter something to encypt: ")
translated = '' 

for i in range(len(message)):
    translated = translated + message[i] 
    i = i - 1 
print(translated)

Good luck!

Hi, I added parentheses to the print (i'm using python 3.3) and i got this error message: Traceback (most recent call last): File "C:/Python33/encryptiontest.py", line 1, in x="hello world".encode("rot-13") TypeError: encoder did not return a bytes object (type=str) >>> – Matthew Mellea Jan 16 '14 at 22:24

Isn't this for string encoding (like going from utf to ascii) not encryption? – wnnmaw Jan 16 '14 at 22:36
meh rot13 is simple encryption ... – Joran Beasley Jan 16 '14 at 22:36
