Untranslate Tools for Cryptography, This made for string chars that was translated with string.translate from python modules.

For my stack, i think why me not build a program un-translate for it? 

1. Stack Problem

>>> import string
>>> make_trans = string.maketrans('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz',
                                  'CDEFGHIJKLMNOPQRSTUVWXYZABcdefghijklmnopqrstuvwxyzab')
>>> trans = string.translate("Summon Agus", make_trans)
>>> trans
'Uwooqp Ciwu'
>>> 

Yup, 'Uwooqp Ciwu' its my problem. 

2. Test It

[email protected]:~/Python-Code/Translate$ python un_translate.py right 3 "Uwooqp Ciwu"

[email protected]:~/Python-Code/Translate$ python un_translate.py left 4 "Uwooqp Ciwu"
Tvnnpo Bhvt
Summon Agus

3. Find Solved

'Uwooqp Ciwu' is 'Summon Agus', beautiful right? 

And thereis script to un-translate of it, save this with name un_translate.py or else, you can chmod it with 777 to make it executable.
or directly with python commands in your terminal like this: $ python un_translate.py

#!/usr/bin/python
# -*- coding: utf-8 -*-
import string, sys
