*Facepalm* (Sorry About The Meme)

Well, I came to a sudden realization shortly after my post on Saturday — because ROT13 is its own solver, I didn’t need any loops at all for encoding vs. decoding ROT13, just a single function 😳 . And even more horrifying was the next realization — I didn’t even need to have two separate ROT13 programs in the first place AT ALL! Wow. That makes me feel good about myself.

So… here is the “all I ever really needed to do” update, rot13er.v1-0-1.py:

ROT13er v1.0.1

# imports maketrans capability & generate ROT13 translation table

from string import maketrans

rot13table = maketrans("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz",\

# user interface and encoding magics

print "ROT13er v1.0.1"
print "Copyright 2010 by Benjamin Braithwaite"
print "A simple ROT13 translator"
toberotted = ""
while not toberotted.strip():
    toberotted = raw_input("Enter your text (ROT13 or plaintext): ")
print toberotted.translate(rot13table)

# successful exit dialog

raw_input ("Press <enter> to exit.")

You can download rot13er.v1-0-1.py from my Dropbox.

It’s the simple things that get you.
